Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a suction panel opening/closing device for an air cleaner.

[Conventional technology]

In conventional air purifiers, the front surface of the main body case, which has a discharge port for clean air, is covered with a suction panel for sucking in dust-containing air, and this suction panel is equipped with a rotating fulcrum part provided on the left and right edges of the suction panel. Some are made to open and close with

[The problem that the idea aims to solve]

In the above-mentioned conventional air purifier, if the suction panel has a curved shape in which the central part of the panel surface protrudes more forward than the left and right side parts, the rotational fulcrum part is placed between the left and right side edges of the panel. No matter where you set it, the protruding part at the center of the panel hits the front edge of the main case, making it impossible to open the panel. Therefore, although it is possible to open the panel by setting the rotation fulcrum at one location on the protruding part at the center of the panel, in this case, the entire panel is supported at one location, so the panel is likely to wobble when opened and closed. In addition, there was a drawback that overload was applied to the rotational fulcrum part due to carelessness when handling the panel, and there was a risk of damage to the fulcrum part.

An object of the present invention is to provide a suction panel opening/closing device that can eliminate the above-mentioned conventional drawbacks.

[Means to solve the problem]

The present invention will be described in detail below based on the drawings. Reference numeral 1 denotes a main body case, which has a clean air outlet 21. Reference numeral 2 denotes a suction panel that covers the front surface of the main body case 1, and is shaped so that the central portion thereof protrudes further forward than the left and right side portions. 3, 3 is a rotation fulcrum provided near the lower end of both left and right edges of the panel 2;
Reference numeral 4 denotes a slide stay, the tip portions 5, 5 of which are connected to the rotation fulcrum portions 3, 3. Reference numerals 6, 6 denote frames that support the slide stays 4, 4 so that they can slide freely toward the front of the main case 1, and are attached to both left and right portions of the main case 1. 7, 7 are springs suspended between the slide stays 4, 4 and the frames 6, 6, which always urge the slide stays 4, 4 forward of the main body case 1. Reference numeral 8 denotes a locking mechanism connected to each slide stay 4, 4, including a locking piece 9 that locks each slide stay 4, 4 in the pushed-in position, and a locking piece 9 that locks each slide stay 4, 4 by this locking piece 9. It consists of an operation piece 10 that is operated to release the lock.

[Effect]

When each slide stay 4, 4 is pushed in against the elasticity of the springs 7, 7, each slide stay 4, 4 is locked by the locking piece 9, and at the same time, the rotation fulcrum parts 3, 3 are moved to the main body case 1. Therefore, even if an attempt is made to open the panel 2, the central protrusion 20 of the panel 2 hits the front edge of the main body case 1 and cannot be opened.

In this state, when the slide stays 4, 4 are unlocked with the operating piece 10, the elasticity of the springs 7, 7 acts on each slide stay 4, 4, pushing them forward of the main body case 1, and at the same time, Since the rotation fulcrum parts 3, 3 move forward,
The central protruding portion 20 of the panel 2 no longer abuts against the front edge portion of the main body case 1, and the panel 2 can be opened.

〔Example〕

The rotation fulcrum parts 3, 3 may be removably connected to the tips 5, 5 of the slide stays 4, 4,
They may also be permanently connected. Lock mechanism 8
For example, as shown in FIGS. 4 to 6, the intermediate portion 12 of the locking piece 9 is engaged with the fulcrum part 13 provided at the rear end of the frame 6, and the rear end of the locking piece 9 is provided with a slide stay. 4 is provided with an engaging end 15 that can be engaged with the elongated hole 14 bored in the frame 6, and the end of the shaft 16 attached to the frame 6 and the elongated hole 14 is passed through the distal end of the locking piece 9. A spring 17 is interposed between the frame 6 and the tip of the locking piece 9 on the shaft 16 to urge the engaging end 15 of the locking piece 9 to engage with the elongated hole 14 at all times. A push button 18 is attached to the end of the shaft 16 to press the tip of the locking piece 9 against the elasticity of the spring 17. When this push button 18 is pressed, the engaging end of the locking piece 9 is pressed. 15 is configured so that it is separated from the hole end 19 of the elongated hole 14.

[Effect of idea]

Since the present invention is constructed as described above, the fulcrums of the curved suction panel that covers the front surface of the main case are dispersed to the left and right, and they are pushed forward by operating the operation piece, so the suction panel is It has the advantage of being easy to open and close in a stable state.
