Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a wall-mounted air cleaner.

Conventional technology Conventionally, this type of wall-mounted air purifier
The configuration was as shown in the figure. That is, in the figure, 101 is a blade for blowing air, 102 is a driving motor thereof, 103 is a rear case that forms a casing 105 together with a front case 104 and forms the outer shell of the main body, and 106 is attached to the suction side of the casing 105. , an electrostatic filter that removes dust from the air, 1
07 is a deodorizing filter that is similarly installed on the suction side of the casing 105 and removes odors, 108 is a front grill, 109 is a blowout grill arranged on the suction side of the casing 105, and 110 is a metal fitting attached to the casing 105. , engages with a metal fitting 112 attached to the wall surface 111, and attaches the purifier to the same wall surface 1.
Fixed at 11. In addition, the front grill 108 is
It has a plurality of fitting claws 113 on the upper part and a plurality of similar fitting claws 114 on the lower part, and is secured to the front case 104 by these fitting claws 113 and 114. When replacing the electrostatic filter 106 and deodorizing filter 107, the front grill 108 can be removed by pulling the rib-shaped handle 115 provided at the bottom of the front grill 108 toward you. I was working on it.

Problems that the invention attempts to solve In this conventional configuration, the purifier is placed on the wall 11.
When removing the front grill 108 while still attached to the front grill 1, the parts other than the front grill 108 must be firmly supported and fixed by hand.
That is, when the handle 115 is pulled, the front grill 108 does not come off and the metal fittings 110, 11
If a force is applied to the fittings 110 and 11 and the attachment becomes loose, or if a force is applied upward, the fittings 110 and 11
There was a risk that the fitting of 2 would come loose and the purifier would fall. Furthermore, the part that supports the purifier has no unevenness that can be grasped by hand, so there is the problem that it has to be supported in an unstable state, and there is a handle on the bottom that is easy to see.
15, there was a problem in terms of design as well.

This invention solves these problems,
The purpose is to facilitate the removal of the front grill.

Means for Solving the Problem In order to solve this problem, the present invention includes a blower blade, a motor for driving the blade, a casing containing the blade and the motor, and a casing mounted on the suction side of the casing. an electrostatic filter and a deodorizing filter that purify the air; and a box-shaped front grill with an opening on one side that is removably attached to the casing, and the front grill has a mating claw that engages with the casing. A notch is provided in an upper inner wall portion and a lower left and right inner wall portion, and a U-shaped notch is formed by cutting out an opening end side of the front grill from a fitting claw provided in the lower left and right inner wall portions, and The casing is provided with an elastic piece having a receiving tab that fits into a fitting tab provided on the lower left and right inner walls of the front grill, and a presser portion exposed from a notch of the front grill.

Function: With this configuration, by pressing the presser parts exposed from the notch of the front grill on the left and right sides at the same time and bending the elastic pieces, the elastic pieces fit into the fitting tabs provided on the lower left and right inner walls of the front grill. The catch tab that was holding the front grille can now be removed.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 5. In the figure, 1 is a blade for blowing air, 2 is a driving motor thereof, 3 is a rear case which forms a casing 5 together with a front case 4 and forms the outer shell of the main body, 6 is attached to the suction side of the casing 5,
An electrostatic filter 7 removes dust from the air, a deodorizing filter 7 is similarly attached to the suction side of the casing 5 and removes odors, and 8 is a box-shaped front grill with an opening on one side that is removably attached to the casing. , 9 is an air outlet grill arranged on the air outlet side of the casing 5, and 10 is a metal fitting attached to the rear case 3, which is fitted with a metal fitting 12 attached to the mounting wall surface 11 to fix the main body to the mounting wall surface 11. . Next, the fixing structure of the front grill 8 will be explained. The front grill 8 has two convex fitting tabs 13 on the upper inner wall and one convex fitting tab 14 on each of the lower left and right inner walls. Then, from the fitting claw 14 on the lower inner wall portion, the front grill 8
A notch 19 is formed by cutting out the open end side of the opening end in a U-shape. On the other hand, the upper part of the front case 4 forming the casing 5 is provided with a fitting receiving claw 15 formed in an upward concave shape into which the fitting claw 13 provided on the front grille 8 is fitted. On the left and right sides of the lower part, there are receiving claws 17 that fit into the fitting claws 14 provided on the front grille 8, and cutout portions 1 of the front grille 8.
An elastic piece 16 having a presser portion 18 formed with a plurality of convex rib groups exposed from the elastic piece 9 is provided. Reference numeral 20 denotes a rib for positioning the front grille 8 in the vertical direction.

In the above configuration, when attaching the front grill 8, fit the fitting claws 13 provided on the upper inner wall of the front grill 8 into the fitting receiving claws 15 provided on the front case 4 of the casing 5, and then The fitting claw 14 provided on the inner wall of the casing 5
A presser foot is provided on the casing 5 side of the notch 19 formed in the front grille 8 by pressing the front grille 8 toward the casing 5 side so as to fit against the elastic force of the elastic piece 16 provided on the side. Attach so that part 18 is exposed.

Next, when removing the front grill 8, press inward the presser part 18 provided on the elastic piece 16 exposed through the notch 19 formed in the front grill 8. If the lower part of the front grill 8 is pulled toward you in this state and the front grill 8 is lifted upward, the upper fitting claw 13 will be released from the receiving claw 15. It comes off.

At this time, since the fitting receiving claws 17 are provided on the left and right sides, if you press the holding parts 18 on the left and right sides at the same time, the front grill 8 can be easily removed without tilting the main body of the air cleaner and in a stable state. It is something that can be done. In particular, in a wall-mounted air purifier, it is necessary to periodically replace the electrostatic filter 6 and deodorizing filter 7 while it is mounted on the wall surface 11, and it is desirable that the front grill 8 can be easily attached and detached. According to the above, there are problems such as the front grille 8 being difficult to remove unless the main body is firmly supported by hand as in the past, and the main body being insufficiently supported and lifting upwards and falling.
The front grill 8 can be easily removed without fear of the mounting fittings 12 coming loose. In addition, it can be installed in the same way as the traditional method,
It's easy. Furthermore, there is no need to provide a convex or concave handle for pulling and removing the front grille 8 on the lower surface of the product, which is easy to see as in the past, and there is an advantage in terms of design. be.

Effects of the Invention As is clear from the above embodiments, according to the present invention, a notch is provided in the fitting claw portion of the front grill, and a presser portion exposed from the notch and the fitting claw are provided on the casing side. An elastic piece is provided with a receiving claw that fits into the front grill, and the front grill can be removed by operating the holding part.
Since the front grill can be easily removed in a stable state without having to firmly support the main unit attached to the wall with one's hands, the electrostatic filter and deodorizing filter can be easily replaced. Moreover, there is an effect that there is no danger of the main body shaking and falling.
