Description

TECHNICAL FIELD The present invention relates to an air purifier.

2. Description of the Related Art In recent years, ceiling-embedded air purifiers have been developed to purify indoor air.

Conventionally, this type of air purifier has a configuration as shown in FIGS. 4 to 6. That is, the blower device 1 including the blades 103 and the motor 104 on the upper portion of the main body 102 embedded in the back of the ceiling 101.
05 is built in, and a dust collection unit 106 is provided on the side of the suction port opened below the blower 105. A grill unit 107 is installed below the dust collecting unit 106 so as to be substantially flush with the ceiling 101, and a suction grill 108 provided at the center of the grill unit 107.
The dirty air in the room is sucked from the air and is purified by the dust collecting unit 106, and then passes through the air blower 105 and the grill unit 1
The clean air was returned to the room through the air outlet 109 provided so as to surround the outer periphery of 07. The dust collection unit 106
Is placed on the inner lid 110, and one end of the inner lid 110 is rotatably attached to the main body 102 via a hinge. An inner lid support plate 115 is fixed in the vicinity of the other end of the inner lid 110 by protruding upward.
A sliding shaft 114 horizontally projects above the inner lid support plate 115. A bar plate-shaped side stay 111, one end of which is rotatably supported by a main body 102 via a stay support pin 112, has a slit 113 along the center line in the longitudinal direction, and the side cover 111 of the inner lid support plate 115 The sliding shaft 114 is slidably inserted into the slit 113, and the side stays 111 are fixed substantially horizontally as shown in FIG.

In the above structure, when the dust collecting unit 106 is replaced, the suction grill 108 and the inner lid 110 are unlocked and rotated downward, respectively. However, it was held in a state of being engaged with the end of the slit 113 of the side stay 111 and opened downward by a predetermined angle. Then, the dust collecting unit 106 was slid on the inner lid 110 and pulled out to perform replacement.

Problems to be Solved by the Invention In such a conventional configuration, the dust collection unit can be replaced because the inner lid 110 can be opened only at a fixed angle, but the dust collection unit 106 inner wall portion of the storage portion during cleaning is possible. It is very difficult to wipe off the dirt on the blade 103, the motor 1
It is impossible to replace parts such as 04. Therefore, the inner lid 110 is to be removed. At this time, the sliding shaft 114 or the inner lid supporting plate 115 is disassembled, or a round hole 116 for removing the sliding shaft 114 is formed as a side stay as shown in FIG. 11
There is a method of providing it in a part of the slit 113 of 1. However, in the method of disassembling the sliding shaft 114 and the like, there are problems that the number of man-hours for disassembling and assembling increases, and the scaffolding is unstable, so that workability is poor and there is a danger. Further, in the method of providing the hole 116 to which the sliding shaft 114 is attachable / detachable in a part of the linear slit 113, the sliding shaft 114 is opened while the inner lid 110 is opened.
There is also a possibility that the dust may naturally come off from the hole 116, and at this time, the inner lid 110 is suddenly opened and there is a risk that the dust collecting unit 106 may fall.

The present invention solves the above-mentioned conventional problems, and an air cleaner that can easily clean the inside of the main body and inspect and replace parts by providing a structure in which the inner lid can be safely and easily attached to and detached from the side stays. The purpose is to provide.

Means for Solving the Problem In order to solve the problem, the present invention provides an air blower incorporated in a main body, and a dust collecting unit arranged on the suction side thereof.
An inner lid on which the dust collecting unit is placed and one end of which is rotatably supported by the main body, a sliding shaft protruding from the inner lid, and a large diameter provided at the tip of the sliding shaft. And a L-shaped side stay whose one end is rotatably supported by the main body, an L-shaped slit provided along the longitudinal centerline of the side stay, and an end of this slit. A slide hole of the inner lid is slidably inserted into the slit of the side stay, and the slide shaft of the inner lid is slidably inserted into the slit of the side stay. The tip is detachable from the slit at the position of the hole at the end of the slit.

Action With this configuration, the sliding shaft of the inner lid support plate is temporarily locked by the curved portion of the slit of the side stay, and then the side stay is pushed up, so that the sliding shaft slides to the lower end of the slit, The sliding shaft can be removed from the hole.

EXAMPLE An example of the present invention will be described below with reference to FIGS. Here, detailed description of the same configuration as the conventional example will be omitted.

As shown in the figure, the air purifier of the present invention has a blower unit 5 built in the upper part of a main body 2 buried in the back of a ceiling 1 as in the conventional example, and a dust collecting unit 6 and a suction unit on the suction side of the blower unit 5. It has a grill 8 and returns the cleaned air to the room through air outlets 9 provided on the entire circumference of the grill unit 7. The inner lid 11 on which the dust collecting unit 6 is placed and whose one end is rotatably attached by a hinge 10 includes a suction grill 8 and an inner lid 11.
When the lock is released, the sliding shaft 16 of the inner lid support plate 13 engages with the slit 15 of the side stay 12 as shown in FIGS. 2 and 3, and the inner lid 11 is tilted downward at a certain angle. Supported.
Here, the side stay 12 has a downward L shape, and one end thereof is rotatably supported by the main body 2 by a stay support pin 14. Further, the side stay 12 has an L-shaped slit 15 along the center thereof, and a sliding shaft 16 provided on the inner lid 11 is slidably fitted in the slit 15. Sliding axis
The tip of 16 has a tip 16-a having a diameter larger than the width of the slit 15. At the lower end of the slit 15, a hole 17 having a diameter larger than that of the tip portion 16-a of the sliding shaft 16 is opened.

The operation of the above structure will be described below. When the side stay 12 is slid upward until the sliding shaft 16 is aligned with the hole 17 with the inner lid 11 opened as shown in FIG. The moving shaft 16 and the rotary support 12 can be disengaged. As a result, the inner lid 11 can be opened greatly downward, which facilitates the cleaning work of the dust collecting unit 6 housing portion of the main body 2, and the suction nozzle 18 can be attached and detached to maintain the blades 3 and the motor 4 for maintenance and inspection. Parts replacement work can be performed easily.

In the embodiment, the ceiling-embedded air purifier in which the main body is embedded in the ceiling is described, but the same effect can be obtained in a ceiling-suspended air purifier in which the main body is mounted below the ceiling surface. .

As described above, according to the present invention, an L-shaped slit is provided in a downward L-shaped side stay, and a circular hole is formed at the lower end of the slit so that the support shaft can be attached and detached. The present invention provides an excellent air purifier that can be easily and safely separated from the above, and has the effect of easily cleaning the dust collecting unit housing portion of the main body and replacing parts such as blades and motors.
