Description

[Detailed explanation of the idea] Industrial applications The present invention relates to an air cleaner.

Conventional technology A conventional air purifier is provided with a suction grill and a discharge grill on the front of the case body, and a portion of the inside of the case body close to the suction grill has a charged part and a part of the case body that is close to the suction grill. A dust collection section is provided, which consists of a collection section that collects charged dust particles as they pass through, and a high voltage device is connected to this dust collection section, and the dust collection section and the back of the case body are Some have a fan connected to a motor between the covering backboards.

In this air purifier, the fan suctions dust-containing air so that it passes through the suction grill and the dust collection section in that order, and then the purified air is passed through the discharge grill in the process of passing through the dust collection section. It is necessary to provide a passageway.

Conventionally, this purified air passage was formed by pressing the edge of an air passage wall that spirally surrounds the outer periphery of the fan against the inner surface of a back plate that covers the back surface of the case body.

Problems to be solved by the invention In the conventional air purifier described above, when forming the purified air passage, a sealing process is required to airtightly press the edge of the air passage wall against the inner surface of the back plate of the case body. There was a problem that it took time and effort to assemble the air purifier.

The present invention aims to provide an air cleaner that can solve the above-mentioned conventional problems.

Means for Solving the Problems The present invention will be explained in detail below based on the drawings. 1 is a case body, 2 is a front door that covers the front side of the case body 1 from the lower side to the upper side, A suction grill 3 is provided. A cover body 4 covers a portion of the front side of the case body 1 above the front door 2, and is provided with a discharge grille 5. Reference numeral 6 denotes a dust collection section provided inside the case body 1 at a location close to the suction grill 3, which collects dust particles that are charged during the process of the dust-containing air 29 passing between the charging section 7 and the charging section 7. It has a built-in collection part 8 that can be taken out. 31 is a high voltage device connected to the dust collection section, 9 is a back plate that covers the back of the case body 1, and 10 is a dust collection section 6
11 is a fan 10 provided between the back plate 9 and the
12 is a motor connected to a dust collecting section 6 and a fan 1.
The suction port 13 of the fan 10 is a partition wall provided between the
An air inlet 14 communicating with the air outlet 14, an air outlet 15 communicating with the discharge grille 5, and an air passage wall 16 spirally surrounding the fan 10 from the outer periphery of the fan 10 to the air outlet 15 are provided. 17 is a groove provided on the inner surface of the back plate 9 so that the entire edge of the air passage wall 16 can be inserted; 18 is a guide protrusion provided here and there in the groove 17 to guide the edge of the air passage wall 16 into the groove 17; It is designed to be installed. 28 is a lead wire for supplying electricity to the motor 11.

Function: Attach the back plate 9 to the case body 1, then attach the partition wall 1.
2 into the case body 1 from the front side of the case body 1, the air passage wall 16 is hidden behind the partition wall 12 and cannot be seen, but when the edge of the air passage wall 16 approaches the groove 17, After hitting the guide protrusion 18, the entire edge advances while being guided by the guide protrusion 18, is inserted into the groove 17, and is cleaned by the dust collector 6 between the partition wall 12 and the back plate 9. A purified air passage 19 is formed through which the purified air 30 passes.

Example Case body 1, front door 2, cover body 4, back plate 9,
The partition wall 12 and the air passage wall 16 are made of plastic, for example. The lower part of the front door 2 is connected to the lower part of the case body 1 by a hinge 32, and a bracket 33 is attached to the lower end of the left side edge of the front opening edge of the case body 1, and A bracket 34 is attached to the middle part near the left edge, and a stay 3 is attached to the bracket 33.
A flanged shaft pin 36 is passed through one end of the shaft pin 36, and the end of the stay 35 is somewhat loosely sandwiched between the bracket 33 and the collar of the shaft pin 36. A shaft pin 38 that is slidably fitted into a long hole 37 drilled from the middle part to the other end is attached, and a loop hole is provided in the middle of the long hole 37 through which a collar 39 provided on the shaft pin 38 can pass. 40 is drilled, and at the tip of the long hole 37,
An engaging edge 41 is provided which engages with the shaft pin 38 to lock the front door 2 in the open state when the front door 2 is opened at a certain angle as shown in FIG. Inside the case body 1 are a power transformer, an operating switch, a capacitor connected to the motor 11, and a rectifier circuit board connected between the power transformer, the high voltage device 31, the operating switch, and the capacitor. establish. A plurality of reinforcing ribs 20 are integrally formed on the air passage wall 16 at appropriate intervals. The motor 11 is placed on the inner surface of the back plate 9 at a location facing the dust collection section 6 so that its rotating shaft 21 faces the center of the air inlet 14, and the mounting plate 22 provided on the motor 11 is attached to the back plate 9. Multiple protrusions 2 protruding from the inner surface
3, fix the mounting plate 22 between the protrusions 23 with screws 24, and attach the fan 1 to the rotating shaft 21.
Insert the center part 25 of 0. If the rotary shaft 21 is formed to have the same diameter from the base end to the distal end, the fan 10
This requires a jig to maintain a constant distance between the base plate 9 and the back plate 9, which makes the process that much more troublesome. Therefore, as shown in FIG.
A stepped portion 27 is provided to make the tip end thinner, and the fan 10
By fitting the center part 25 of the fan 10 from the tip of the rotary shaft 21 and abutting it against the stepped part 27, the fan 10 can be easily mounted at a position where a constant distance is maintained with respect to the back plate 9. Partition wall 12
Ribbed spacers 26 are provided protruding here and there on the wall surface facing the back plate 9, and each spacer 2
A protrusion 27 with the tip of 6 provided at a corresponding position on the back plate 9
Insert each into the recesses and secure with screws, etc.

Effects of the invention Since the present invention is constructed as described above, a purified air passage can be formed by simply inserting the edge of the air passage wall provided on the partition wall into the groove provided on the back plate.
The sealing process can be omitted, and the edge of the air passage wall can be easily inserted into the groove by the guidance of the guide protrusion without the need for groping, so the purified air passage can be easily formed and the assembly work of the air purifier can be reduced accordingly. can be streamlined.
