Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air purifier that takes in dirty air in a room and removes dust, smoke, odor, etc. in the air.

2. Description of the Related Art A conventional air purifier of this type has a louver 1 having a lattice formed inside a tubular frame as shown in FIG. That is, the louver 1 was formed in a tubular shape, the shafts 2 were provided at both ends, and the lattice 3 was integrally formed inside thereof. Further, the louver provided at the air outlet of the automobile does not need to be considered to prevent foreign matter from entering, and therefore has no lattice and only the blades are interlocked.

Problems to be Solved by the Invention However, when an air purifier having such a structure is hung on a wall and used, the exhaust port is generally downward and the exhaust gas may hit a person below and feel cold. there were. In other words, in order to remove cigarette smoke, it is often installed near a smoker, and as a result, the exhaust air is blown out to the place where people are, so it feels cold. Although the wind direction could be changed in one direction by the axis, its effect was not sufficient. Moreover, when it was used deferredly, it was necessary to take measures to prevent foreign matter from entering.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a rectangular parallelepiped cylinder for flowing an air flow, and a grid integrally provided with the cylinder so as to cover one end surface of an air flow passage of the cylinder. And a louver composed of a plurality of blades rotatably arranged in the cylinder and a link connecting the plurality of blades, and the louver is arranged in the exhaust portion of the air purifier. A plurality of shaft holes are respectively provided in the opposing walls of the constituting cylinder, and a plurality of blades are rotatably supported in the shaft holes.

Effect The present invention has the above-described configuration, in which the plurality of blades can be rotated in the cylinder, and the entire louver can be rotated by attaching the entire louver to the exhaust portion of the air cleaner. In addition, the blades are inserted by pushing the walls of the cylinders facing each other with the axial holes widened, but the lattice integrally provided so as to cover the front surface of the cylinder on the air flow inlet side and the walls facing each other of the cylinders. Since the push-spreading is prevented, it is possible to prevent the shaft-supported portion from coming off due to the insertion of the blade.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 9, reference numeral 11 forms a box body with the rear of the main body and the front 12 of the main body, and a front glue 13 having a large number of air suction holes 14 on the front is attached to the front 12 of the main body. Reference numeral 15 is a pre-filter for catching relatively large dust such as cotton dust, 16 is a filter case, and a dust collecting filter 17 and a deodorizing filter 18 are built therein. 19 is a partition wall that guides the air flow created by the fan 20 to the exhaust port 21.
22 is integrally formed. Reference numeral 23 denotes a suction port opened in a partition wall, and a motor 25 having a fan 20 attached thereto is fixed to a plurality of arm portions 24 extending toward the opening center of the suction port 23. Reference numeral 26 denotes a louver, which is rotatably held between the rear body 11 and the partition wall 19 and is arranged at the exhaust port 21 of the air purifier. 27 is a switch part mounted in the recess of the rear of the main body 11. When using it on a wall, it is taken out of the recess and attached to the wall surface by connecting it with a cord separately from the main body. 28 is a recess for pulling out the filter case. The louver 26 has, as shown in FIG. 2, a rectangular parallelepiped cylinder for flowing an air flow,
The opposite side walls, that is, the side walls 41 and 41 ', have the shaft 2
9, the protrusion 30 is provided symmetrically. Reference numeral 31 is a grid integrally provided so as to cover one end surface of the air flow passage of the cylindrical body, and this grid 31 prevents foreign matter from entering the air purifier. 32 is a blade arranged inside the cylinder of the louver 26,
As shown in the figure, the blade 32 is fitted in a hole 34 provided in the link 33 so that the small shaft 35 thereof is rotatable and does not come off easily. In addition, the width of the blade 32 on the front side is set to be small and the width of the rear side is set to be wide, and the front end and the rear end respectively have shafts.
36 and 36 'are provided. The facing walls of the louver 26,
Shaft holes 39, 39 'for rotatably supporting the shafts 36, 36' of the blade 32.
2, that is, the front wall and the rear wall of the tubular body of the louver 26 shown in FIG. 2 are set to have a lower front wall and a higher rear wall according to the width of the blade 32. In addition, a part of the blade 32 (the central part in the drawing) and a part of the hole 39 (the central part) are
As shown in FIG. 8, the tip diameter φd 'of the shaft holes 40, 40' is larger than the diameter φd by 0.2 to 0.4.

Next, the assembling method of the above structure will be described. First, as shown in FIG. 3, the small shaft 35 of the blade 32 is fitted into the link 33. Insert the blade 32 connected with the link 33 along the rear wall to insert the shaft hole.
36 'is fitted in each hole 39'. Next, as shown in FIG. 4, the front wall is expanded and the blades 32 are bent and pushed in to fit the shaft hole 36 into the hole 39. Blade shaft hole 36,3
When 6'is fitted into holes 39, 39 'respectively, front wall 37 and rear wall
Pressure is applied from the outside of 38 to push in the shaft holes 40, 40 '.

The louver 26 assembled in this way is
Since the shaft 29 is rotatably held by the partition wall 19, not only the exhaust direction can be freely changed from A to B by moving the entire louver, but also the exhaust angle can be changed left and right by tilting the blades 32. It is what is done.

Further, since the shaft end of a part of the blade is made larger than the hole diameter and is fitted by utilizing the elasticity of the resin, the blade 32 does not easily come off, and the marking 31 is integrally formed. Even in stationary use, it is possible to prevent foreign objects from being inserted by an infant.

As described above, according to the present invention, a lattice is formed at one end of an inlet formed in a rectangular tubular shape, and a windbreak blade is connected to the inside of the tubular cylinder by a link to connect the front wall and the rear wall. The louver can be tilted back and forth, and the blades can be moved left and right because the face wall is pivotally supported and both ends of the cylinder are pivotally supported by the rear of the main body and the partition wall, and the protrusions are fitted into the holes provided in the partition wall. As a result, the exhaust direction can be freely selected in the front, rear, left, and right directions, and the blades can be easily assembled, and when assembled by being sandwiched between the rear of the main body and the partition wall, the blades will not come off. In particular, since a lattice is provided on the inlet side of the cylinder to prevent the front wall and the rear wall of the cylinder from spreading, a plurality of blades are supported in shaft holes provided in the front wall and the rear wall of the cylinder. After that, the blade can be surely prevented from coming off the shaft hole. Further, since the lattice having the function of preventing the entry of foreign matter is used, the assembly is easy without newly using a reinforcing member. In addition, since there is a grid, when the air purifier is used in a stationary manner, even if a small child tries to put in an object through the exhaust port, the grid prevents the intrusion of foreign matter that affects the performance such as fan lock.
