Next, the locking mechanism of the cover 39 installed in the opening 38 of the front panel 37 will be described in detail.
First, as shown in FIG. 6, the cover 39 has a display window 62 opened so that the display surface 56 on the operation unit 4 can be seen when the cover 39 is closed, and a cover 39 on the right side of the cover 39. The cylinder 64 that can be locked with the key 63 so that it cannot be rotated and opened, and is on the left side of the cover 39 when viewed from the front and is orthogonal to the cover 39 toward the rear side of the cover 39. The cover end surface 72 that is erected, the L-shaped corner 73 that is bent at a right angle in a direction parallel to the cover 39 from the cover end surface 72, and the L-shaped corner connected to the L-shaped corner rotate when the cover 39 is opened and closed A claw 65 that serves as a fulcrum for supporting the cover 39 is formed.

Further, when the cover 39 is installed in the opening 38, the front panel 37 is removed from the instrument body 1, and the operation is performed on the operation part mounting plate 74 to which the operation part 4 located behind the front panel 37 in the instrument body 1 is attached. A leaf spring 66 serving as a fixed end 68 with one end fixed by a screw 67 is attached to a position about 1 cm away from the operation unit end surface 4 a which is a side end surface of the unit 4.
The leaf spring 66 extends in the direction of the operation portion end surface 4a from the fixed end 68 while being adjacent to and parallel to the operation portion mounting plate 74, and bends forward of the instrument body 1 just before it abuts against the operation portion end surface 4a. In addition, it is attached so as to form a free end 69 that extends to the front side of the instrument body 1 while adjoining in parallel with the operation portion end surface 4a and protrudes further forward from the front end surface of the operation portion end surface 4a. It is substantially L-shaped in plan view.

  When the fixed end 68 of the leaf spring 66 is installed on the operation portion mounting plate 74 with the screw 67, the front panel 37 is erected in the inner direction of the instrument body 1 so as to be at the side end face of the opening 38 and to be orthogonal to the front panel 37. The cover 39 is installed on the opening 38 by inserting a claw 65 smaller than the diameter of the claw hole 71 into a claw hole 71 formed on the panel end surface 70 which is an end of the claw.

  When the front panel 37 with the cover 39 installed in the opening 38 is attached to the front surface of the instrument body 1, as shown in FIG. 7, a plate protruding further forward from the front end face of the operation portion end face 4a. The free end 69 of the spring 66 comes into contact with the cover end surface 72 of the cover 39 facing the operation portion end surface 4a, and the cover end surface 72 is biased toward the panel end surface 70 by the free end 69.

  As described above, the cover end surface 72 is biased by the free end 69 of the leaf spring 66, so that the user has an end surface opposite to the cover end surface 72 and moves the cover 39 toward the front side of the instrument body 1. When the operating portion 4 is opened by rotating the cover, the cover end surface 72 is urged toward the panel end surface 70 by the free end 69 of the leaf spring 66, so that the right side of the cover 39 where the claw 65 is not formed is shown. Can be prevented from tilting due to its own weight.

  When the cover 39 is opened to operate the switch on the operation unit 4, the cover end surface 72 rotates to deform the free end 69 of the leaf spring 66, and an L-shape that connects the cover end surface 72 and the claw 65. The change of the position of the corner 73 determines whether the cover 39 is opened or closed.

  That is, as shown in FIG. 8, when the cover 39 is rotated from the closed state to the fully opened state, the L-shaped corner 73 draws a semicircular locus, and the free end 69 of the leaf spring 66 is L-shaped. Since the corner 73 is urged toward the panel end surface 70, the L-shaped corner 73 is positioned at the apex of the locus (2) (the opening angle formed by the front panel 37 and the cover end surface 72 is 45 °). ), The cover 39 is closed and the L-shaped corner 73 is located on the one side of the locus (1), or the cover 39 is fully opened and the L-shaped corner 73 is located on the other end of the locus ( Whether the cover 39 is operated in the opening direction or the closing direction of the cover 39 is determined depending on the position 3).

  Accordingly, when the L-shaped corner 73 is positioned between the state (2) which is the apex of the locus of the L-shaped corner 73 and the state (1) where the cover 39 is closed, the free end 69 of the leaf spring 66 causes the L-shape. Since the corner 73 rotates toward one end side of the locus, the cover 39 rotates toward the closed state.

  Further, when the cover 39 is positioned between the state (2) which is the apex of the locus of the L-shaped corner 73 and the cover 39 is fully opened (3), the L-shaped corner 73 is moved to the L-shaped corner 73 by the free end 69 of the leaf spring 66. Since the cover 39 rotates toward the other end side of the locus, the cover 39 rotates toward the fully opened state.

  Therefore, as shown in FIG. 9, the opening angle X, which is the angle formed by the front panel 37 and the cover end surface 72, exceeds a predetermined value of 45 °, which is the opening angle when the L-shaped angle 73 becomes the apex of the locus. In this state, the free end 69 urges the L-shaped corner 73 to the position when the cover 39 is closed, so that the operation of closing the cover 39 is assisted.

  Also, as shown in FIG. 10, when the opening angle X is less than a predetermined value of 45 °, which is the opening angle when the L-shaped angle 73 becomes the apex of the locus, the L-shaped angle is set by the free end 69. Since 73 is urged to the position when the cover 39 is fully opened, the operation of opening the cover 39 is assisted.

  As described above, when the cover 39 is installed in the opening 38 of the front panel 37 and attached to the instrument main body 1, the free end 69 of the leaf spring 66 attached to the operation unit mounting plate 74 in the instrument main body 1 is covered by the cover 39. By installing the end face 72 so as to urge the panel end face 70 side, when the cover 39 is opened, the L-shaped corner 73 connecting the cover end face 72 and the claw 65 is formed by the free end 69 of the leaf spring 66. Since the cover end surface 72 is urged toward the panel end surface 70 by being biased toward the 70 side, the end side opposite to the cover end surface 72 is not inclined due to the weight of the cover 39, and the cover 39 can be smoothly moved. It became possible to open and close.

When the cover 39 is opened, the cover 39 is opened by the leaf spring 66 when the opening angle formed by the front panel 37 and the cover end surface 72 exceeds the opening angle at the position where the L-shaped angle 73 is the apex of the locus. Since the cover 39 is biased in the direction, the opening operation of the cover 39 can be performed without applying force by the user, and the usability is improved.
When the cover 39 is closed, the cover 39 is closed by the leaf spring 66 when the opening angle formed by the front panel 37 and the cover end surface 72 is less than the opening angle at the position where the L-shaped angle 73 is the apex of the locus. Since it is biased in the direction, the user can carry out the closing operation of the cover 39 without applying force, and the usability is improved.

  Further, the leaf spring 66 is formed with a convex portion 76 that engages with a small hole 75 formed in the inside of the instrument body 1 in the vicinity of the fixed end 68 fixed with the screw 67, so that the cover spring 39 is opened and closed. Even if a force is applied to the leaf spring 66 in the vertical direction, the protrusion 76 is engaged with the small hole 75 to prevent the movement in the vertical direction, and the leaf spring 66 uses the screw 67 as a fulcrum. Prevents rotation.

  Further, since the cover end surface 72 of the cover 39 is constantly urged toward the panel end surface 70 by the free end 69 of the leaf spring 66, the mist motor 14 and the blower fan installed in the instrument body 1 when the cover 39 is opened and closed. Even if a drive component such as 17 is driven to generate vibration, the cover 39 is fixed by the urging force of the leaf spring 66, so that the cover 39 is not affected and the feeling of use is not hindered.

  In addition, although this embodiment demonstrated the latching mechanism of the cover 39 installed by retrofitting to the operation part 4 of a humidifier, it is not restricted to this, The cover installed on housing | casings, such as a hot-water supply apparatus and a heating apparatus It is a structure applicable also about 39, and the content limited to a humidification apparatus is not intended.

  Further, the configuration and control contents in the present embodiment are presented as examples, and are not intended to limit the scope of the invention, and can be implemented in various other forms. Various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
