Abstract

PROBLEM TO BE SOLVED: To correct a suction grill to a normal form at the time of mounting the grill at a body case even in case of a partly deformed grill by providing a warp correcting unit for pressing a rear surface of a wall of the grill at the case having a suction port and a discharge port. SOLUTION: A body case 1 of the air cleaner is constituted by a front case 2 and a rear case 3. The case 2 has two ribs 5 provided at a surface opposed to a lower end face of a suction grill 4. And, a warp correcting unit 8 is provided at an upper part surface of a front surface part of the case 2. In the case of mounting the grill 4 at the case 1, a fixed rib 15 of the grill 4 is latched to the rib 5. With the rib 15 used as a fulcrum, the grill 4 is rotated to be mounted at the case 1. At this time, a rear surface of an upper side wall 4a of the grill 4 is urged upward by the unit 8. Accordingly, even if warp is generated at the wall 4a, the rear surface of the wall 4a is pressed by the unit 8 to be corrected to a normal form.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIGS.

The main case 1 is composed of a front case 2 and a rear case 3
It is composed of The front surface of the front case 2 has an opening serving as a suction port, and has a substantially concave shape so that the suction grill 4 can be attached to the opening. Also, before case 2
As shown in FIGS. 3 and 4, two ribs 5 are provided on the surface facing the lower end surface of the suction grille 4, and holes are formed at both upper positions on the front surface as shown in FIGS. 6, and an engagement portion 7 having a triangular cross section is provided inside the hole 6. Also, the front case 2 is provided with a convex warpage correcting portion 8 on the upper surface of the front portion. On the back side of the front case 2, there is provided a blower unit 11 including a drive motor 9 and a sirocco fan 10 fixed to a rotating shaft of the drive motor 9. The rear case 3 is formed in a substantially box shape so as to surround the blower unit 11, and has an outlet 12 on an upper surface thereof.

As shown in FIG. 2, the suction grill 4 has an arc-shaped front portion and a filter holding wall 14 for holding a filter 13 on the back side. As shown in FIGS. 8 and 9, a fixed rib 15 that engages with the rib 5 of the front case 2 is provided on the lower end surface of the filter holding wall 14. As shown in FIGS. 6, 7 and 10, the suction grill 4 is provided with a hook 16 which is engaged with the engaging portion 7 of the front case 2 at an upper side.

In the figure, reference numeral 17 denotes a power cord having a connection plug at an end. Reference numeral 18 denotes an operation switch for switching the operation mode between “continuous operation mode”, “constant time operation mode (here, 10 minutes)” and “off”. Reference numerals 19a and 19b denote operation mode display sections composed of LEDs.
When lit, indicates that the `` continuous operation mode '' has been selected.When lit, the operation mode display section 19b indicates that the `` constant time operation mode '' has been selected, and both operation mode display sections 19a, 19b When the light is turned off, the state of “off” is shown. 20
Is a timer switch for setting three types of operation times (here, 1 hour, 2 hours, 4 hours) when the "continuous operation mode" is selected. Reference numerals 21a, 21b, and 21c denote operating time setting display portions each including an LED. When the operating time setting display portion 21a is lit, it indicates that continuous one-hour operation is selected.
When the operation time setting display section 21b is lit, it indicates that the continuous two-hour operation is selected, and the operation time setting display section 21c
Indicates that continuous four-hour operation is selected. When all of the operation time setting display parts 21a, 21b, and 21c are turned off, continuous operation is continued unless the operation switch is turned off. It has become.

Next, the attachment of the suction grill 4 to the main body case 1 will be described. When mounting the suction grille 4 on the main body case 1, the fixing ribs 15 of the suction grille 4 are hooked on the ribs 5 of the front case 2, and the suction grille 4 is rotated with this as a fulcrum (FIG. 12), and mounted on the main body case 1. I do. In this mounted state, the hook 16 is engaged with the engaging portion 7, and the back surface of the upper side wall portion 4 a of the suction grill 4 is pressed upward by the warp correcting portion 8. If the wall 4a is warped when the suction grill 4 is formed,
4 is mounted on the main body case 1, the back surface of the wall portion 4a is pressed by the warp correcting portion 8 so as to be corrected into a normal form.

As described above, in the present embodiment, the suction grill 4
Even if warpage has occurred on the wall 4a, the warp correcting portion 8 provided on the main body case 1 presses the back surface of the wall 4a to correct the warp into a regular shape, so that the shape of the suction grille 4 at the time of molding can be reduced. Guarantee can be made possible.

Next, a second embodiment of the present invention will be described with reference to FIG. Note that members having functions substantially similar to those of the above embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the present embodiment, an engaging portion 22 is provided on the upper part of the warp correcting portion 8 of the first embodiment, and the wall portion 4a of the suction grill 4 is provided.
A hook 23 that engages with the engaging portion 22 is provided at the tip of the hook. In addition, a concave portion 24 is provided on the back surface of the wall portion 4a of the suction grill 4 so as to abut on both side surfaces of the warp correcting portion 8, and the warp correcting portion 8 fits into the concave portion 24. The position of the suction grille 4 is regulated.

As described above, in the present embodiment, the warp correction unit 8
By using this, it is possible to prevent the suction grille 4 from being carelessly detached from the main body case 1 and to regulate the position of the suction grille 4 so that it can be accurately mounted on the main body case 1.

[0017]

According to the air purifier of the present invention, the warp correcting portion provided on the main body case presses the back surface of the wall even if the wall protruding inward of the suction grill is warped. Then, it is possible to guarantee the shape variation at the time of molding the suction grille.

According to the air purifier of the second aspect, in addition to the effect of the first aspect, it is possible to prevent the suction grill from being accidentally detached from the main body case with a simple configuration.

According to the air purifier of the third aspect, in addition to the effects of the first and second aspects, the suction grill is accurately mounted on the main body case by the warp correcting section, and the warp correcting section is securely connected to the suction grill. The back surface of the wall can be pressed.
