Description

Air purifier {Air cleaning apparatus}

The present invention relates to air purifiers.

An air purifier is a device that improves indoor air quality by sucking in indoor air polluted by dust and other contaminants, purifying it, and then discharging the purified air indoors.

Generally, an air purifier includes a filter that collects contaminants contained in the air and purifies the air, a blower fan that provides suction power to suck in indoor air, and discharges the air purified by the filter back into the room. It includes a drive motor that rotates the fan, and a housing in which various parts included in the air purifier, such as the filter, blower fan, and drive motor, are installed.

Recently, a tower-type air purifier has been developed and used to purify air brought in from the room through a suction hole formed on the side and/or bottom of the housing using a filter and then discharge it back into the room through a discharge grill installed on the top of the housing. there is.

However, in the tower-type air purifier, the discharge grill is formed to be open toward the top of the air purifier, and contaminants such as dust that settles on the discharge grill from the air when not used for a long period of time and liquid spilled on the discharge grill due to the user's carelessness are removed. As a result, the discharge grill, the internal flow path of the air purifier connected to the discharge grill, the blower fan, and other parts installed in the internal flow path may become contaminated. In addition, due to changes in the shape of the filter due to long-term use, the internal flow path and parts installed in the internal flow path may be contaminated due to contaminants contained in the air that does not pass through the filter and enters the internal flow path as is.

In a conventional tower-type air purifier, a suction hole is formed, and the panel mounted on the side of the housing and the filter installed in the internal flow path to allow the air introduced through the suction hole to pass are separated from the air purifier, and the internal flow path is moved in the horizontal direction of the housing. After opening, the user's hands or cleaning tools had to enter the internal passage opened in the horizontal direction of the housing to clean the internal passage and the parts installed in the internal passage.

Meanwhile, the blower fan is not only installed in the internal flow path to face the discharge grill, but also has a larger volume than other parts installed in the internal flow path, so it is a tall part that requires the greatest cleaning. However, electrical components such as drive motors and many other components are installed between the opening of the internal flow path that is opened due to the separation of the panel and filter and the blowing fan. Due to this, in order to clean the blower fan and a specific area of the internal flow path adjacent to the blower fan, it was necessary to separate a number of parts, raising the risk of electric shock accidents due to electrical components such as the drive motor, and the separation of electrical components. There was a risk of short-circuiting, disconnection, short-circuiting, or other damage to electrical wiring due to assembly. Due to this, in the conventional tower-type air purifier, the cleaning work of the internal flow path and the parts installed in the internal flow path can only be performed by experts, resulting in the problem that a lot of time and money are spent on maintenance of the product, and the cleaning work is not carried out in a timely manner. There were problems such as difficulty in properly implementing the product, deteriorating sanitary conditions, and frequent breakdowns.

In addition, the conventional tower-type air purifier further includes an inner grill installed inside the housing compared to the discharge grill to block contaminants that are not blocked by the discharge grill and enter the interior of the housing. However, the conventional tower-type air purifier did not include a separate safety device to prevent the inner grill from being arbitrarily separated from the housing. Accordingly, the conventional tower-type air purifier had a problem in that the inner grille was arbitrarily separated from the housing regardless of the user's intention, causing a risk of injury to the user due to externally exposed parts.

To this end, the sensing unit 70 includes a first target member 72 installed at a predetermined position in one of the housing body 11 and the discharge unit 50, and the housing body 11 and the discharge unit 50. ) is installed at another predetermined position among the first sensing member 74 that detects the first target member 72, the discharge unit 50, and the module main body 61. A second target member 76 is installed, and a second sensing member 78 is installed at a predetermined location on the other of the discharge unit 50 and the module body 61 and detects the second target member 76. etc. can be provided.

The controller 80 may determine the installation state of the discharge unit 50 and the input/output module 60 based on signals transmitted by the first sensing member 74 and the second sensing member 78.

For example, when the controller 80 detects the first target member 72 by the first sensing member 74, the discharge unit 50 is coupled to a predetermined reference position of the second opening 11c. It can be determined that the state is in a state, and if the first target member 72 is not sensed by the first sensing member 74, the discharge unit 50 is said to be separated from the predetermined reference position of the second opening 11c. You can judge.

For example, when the controller 80 detects the second target member 76 by the second sensing member 78, the input/output module 60 is seated at a predetermined reference position in the seating groove 52a. It can be determined that, if the second target member 76 is not detected by the second sensing member 78, it can be determined that the input/output module 60 is separated from the predetermined reference position of the seating groove 52a. You can.

Additionally, the controller 80 can control the operation of the air purifier 1 based on the installation status of the discharge unit 50 and the input/output module 60.

For example, if the controller 80 determines that the discharge unit 50 is separated from the predetermined reference position of the second opening 11c, the drive motor 44 and other various devices installed in the internal flow path 11b The operation of the electrical components can be stopped or the power supplied to the electrical components can be cut off.

Then, when the user's hands, cleaning tools, repair tools, etc. enter the internal flow passage 11b through the second opening 11c that opens as the discharge unit 50 is separated, the blowing fan 42 and other electrical equipment It is possible to prevent safety accidents such as injury or electric shock to the user due to the parts.

For example, if the controller 80 determines that the input/output module 60 is separated from the predetermined reference position of the seating groove 52a, the drive motor 44 and other various devices installed in the internal flow path 11b The operation of electrical components can be stopped or the power supplied to the electrical components can be cut off.

As described above, the input/output module 60 is seated in the seating groove 52a in a state in which air A is purified using the air purifier 1 and in other normal use states of the air purifier 1. stored and used. However, when the input/output module 60 is seated in the seating groove 52a, the discharge unit 50 cannot be separated from the second opening 11c due to interference of the input/output module 60. Accordingly, the act of separating the input/output module 60 from the seating groove 52a so that the input/output module 60 does not interfere with the discharge unit 50 is to separate the discharge unit 50 from the second opening 11c. There is great potential for it to be interpreted as prior work for this purpose. Therefore, even when it is determined that the input/output module 60 is separated from the seating groove 52a, the controller 80 operates the drive motor 44 and various other electrical components installed in the internal flow path 11b. It stops or cuts off the power supplied to electrical components.

As above, in the air purifier 1, the input/output module 60 is rotatably hinged to the housing body 11. According to this air purifier 1, the internal flow path 11b, the blower fan 42 installed in the internal flow path 11b, and other parts (hereinafter referred to as 'internal parts') are cleaned or the internal parts are repaired. Or, in case of replacement, the discharge unit 50 is separated from the second opening 11c while the input/output module 60 is rotated so as to be separated from the discharge grill 52, thereby removing the internal flow path 11b and the internal components. It can be exposed to the outside through the second opening 11c.

However, the second opening 11c not only has a relatively short distance between the main work area of the internal passage 11b and the outside, which requires work such as cleaning, repair, and replacement (hereinafter referred to as 'cleaning and other work'). In addition, the number of internal components located between the main work area and the exterior is relatively small. In addition, the second opening 11c is located on the upper surface of the housing main body 11, and the first opening 11a is located on the side or lower surface of the housing main body 11, so that the user can access the housing through the second opening 11c. When approaching the main work area, the main work area can be approached in a relatively more comfortable posture compared to when the main work area is approached through the first opening 11a. Accordingly, the user can use the user's hands, cleaning tools, various tools, etc. through the second opening 11c instead of the first opening 11a to perform the main tasks in the internal flow path 11b in a comfortable position without interference from internal parts. By putting it into the area, cleaning and other work can be easily performed.

In addition, when the second opening 11c is opened or the opening of the second opening 11c is predicted, the air purifier 1 stops driving the electrical components installed in the internal passage 11b or supplies the electrical components to the electrical components. It operates to cut off power. Through this, the air purifier 1 can prevent safety accidents such as injury or electric shock to the user from the electrical components during cleaning or other work.

Generally, the shaft of a motor is made of metal or other conductive conductors. Accordingly, if a user comes into contact with the shaft 44a while performing cleaning or other work on the internal flow path 11b and internal components, there is a risk of electric shock occurring.

To solve this problem, the insulating cover 46 is provided to be axially coupled to the shaft 44a so as to surround at least a portion of the shaft 44a of the drive motor 44. For example, as shown in FIG. 9, the insulating cover 46 may be provided to surround the end of the shaft 44a protruding out of the case of the drive motor 44. This insulating cover 46 is coupled to the outside of the end of the shaft 44a exposed to the outside and isolates the shaft 44a from being exposed to the outside, thereby facilitating cleaning and other work on the internal flow path 11b and internal parts.

When the discharge unit 50 is separated from the second opening 11c and the internal flow path 11b is opened, the blowing unit 40 may be exposed to the outside through the second opening 11c. Accordingly, after separating the discharge unit 50 from the second opening 11c, the user cleans the blowing unit 40 while it is fixedly installed in the housing main body 11, or installs the blowing unit 40 into the housing main body ( Some parts included in the blowing unit 40 can be repaired and replaced while separated from 11).

Hereinafter, a method of separating the blowing unit 40 from the housing main body 11 will be described with reference to the drawings.

First, as shown in FIG. 12, the separation prevention member 48 is rotated in a predetermined direction so that the screw coupling of the first screw thread 46a and the second screw thread 48b is released, thereby removing the separation prevention member 48. It can be separated from the end of the insulating cover 46 that penetrates the end of the shaft hole 42b.

To solve this problem, the hinge coupling structure is such that the air purifier 1 is not exposed to the outside when in the normal use state, but the input/output module 60 is rotated to open the second opening 11c. It is desirable to arrange for limited exposure to the outside.

Hereinafter, with reference to the drawings, the input/output module 60 is designed so that the hinge coupling structure is limitedly exposed to the outside only when the input/output module 60 is rotated to separate from the seating groove 52a of the discharge grill 52. ) and the housing 10 will be described. For convenience of explanation, the position of the input/output module 60 arranged to be seated in the seating groove 52a of the discharge grill 52 is referred to as the 'first reference position' and is positioned so as not to interfere with the discharge grill 52. The position of the input/output module 60 rotated by a predetermined reference angle in one predetermined direction from the 1 reference position will be referred to as the 'second reference position'.

As shown in FIG. 20, the insertion groove 64c is recessed into the inside of the hinge portion 64 to open toward the support member 15 when the input/output module 60 is placed in the first reference position. Additionally, the bracket cover 13b has a first engaging surface 13i formed so that at least a portion thereof is inserted into the insertion groove 64c. Correspondingly, as shown in FIG. 21, the hinge portion 64 has a second lock formed on the outer surface to be caught by the first locking surface 13i when the input/output module 60 is placed in the second reference position. It may further have a surface 64d.

The insertion groove 64c has a predetermined depth so that the inner peripheral surface of the insertion groove 64c does not collide with the first engaging surface 13i when the input/output module 60 is placed at the first reference position. Through this, the insertion groove 64c can prevent the hinge portion 64 and the hinge bracket 13 from being damaged when the inner peripheral surface of the insertion groove 64c collides with the first engaging surface 13i.

In addition, a specific area of the outer surface of the hinge portion 64 that is in contact with the first engaging surface 13i while the input/output module 60 is rotated between the first and second reference positions is the first engaging surface 13i. It is desirable to have a curved shape with a predetermined curvature so that it can slide along.

As described above, the second reference position is the position of the input/output module 60 when the input/output module 60 is rotated by a predetermined reference angle in one predetermined direction based on the first reference position. Here, the reference angle is not particularly limited. For example, the reference angle may be 90°. Then, the second reference position may represent a state in which the input/output module 60 is erected perpendicular to the discharge grill 52. In this case, as shown in FIG. 23, the first engaging surface 13i and the second engaging surface 64d are disposed at the second reference position by rotating the input/output module 60 by 90° from the first reference position. They can be formed so that they are mutually intertwined. Through this, the first engaging surface 13i and the second engaging surface 64d function as stoppers that limit the rotation angle of the input/output module 60 to prevent the input/output module 60 from overrotating beyond the reference angle. can do.

The sensing block 65 may be formed to protrude from the lower surface of the module body 61 so as to be inserted into the first sensing groove 52d of the discharge grill 52 when the input/output module 60 is placed at the first reference position. As shown in FIG. 20, inside the sensing block 65, there is a second sensing member 78 capable of detecting the second target member 76 inserted into the second sensing groove 56c of the inner grill 56. can be installed.

As the second target member 76 and the second sensing member 78 are provided in this way, the second sensing member 78 has the input/output module 60 disposed at the first reference position so that the sensing block 65 is positioned at the first reference position. 1 When inserted into the sensing groove 52d, a detection signal of the second target member 76 can be output and transmitted to the controller 80. Based on the detection signal transmitted in this way, the controller 80 can determine whether the input/output module 60 is placed at the first reference position, that is, whether the input/output module 60 is seated in the seating groove 52a. .

As shown in FIG. 21, the support member 15 of the housing 10 is linked with the guiding surface 66 when the input/output module 60 is rotated to increase the height of the housing body 11 of the input/output module 60. It is a member for inducing movement in a direction (hereinafter referred to as the 'height direction'). This support member 15 has a receiving space formed between the mounting portion 11i and the support member 15 to accommodate the hinge bracket 13 movably in the height direction, and the upper end 15a is an input/output module ( It is mounted on the outer surface of the housing body 11 to face 60).

The guide surface 66 is provided to be continuously supported by the upper end 15a of the support member 15 while sliding along the upper end 15a of the support member 15 when the input/output module 60 is rotated. However, the guide rail 13e of the hinge bracket 13 is coupled to the guide groove 11j of the mounting portion 11i so as to be movable in the height direction. Accordingly, the hinge bracket 13 and the input/output module 60 coupled with the hinge bracket 13 act on the guide surface 66 from the upper end 15a of the support member 15 when the input/output module 60 is rotated. It can move in the height direction due to the reaction force.

More specifically, as shown in FIGS. 20 and 21, the guiding surface 66 moves in advance toward the second reference position so that the input/output module 60 disposed at the first reference position is spaced apart from the seating groove 52a. When rotated in one predetermined direction, the input/output module 60 and the hinge bracket 13 rise toward the upper surface of the housing main body 11, and the input/output module 60 disposed at the second reference position approaches the seating groove 52a. The input/output module 60 and the hinge bracket 13 may be provided to descend toward the lower surface of the housing body 11 when rotated in the other direction opposite to the one direction.

To this end, the guidance surface 66 includes a first guidance surface 66a provided to be supported by the upper end 15a of the support member 15 when the input/output module 60 is placed at the first reference position, and an input/output surface 66a.

It may have a third guide surface 66c, etc. provided to be supported by the upper end 15a of the support member 15 when rotated between two reference positions.

As shown in FIGS. 20 and 21, the first guiding surface 66a is supported by the upper end 15a of the support member 15 when the input/output module 60 is placed in the first reference position. It can be formed on the lower surface of (60).

In addition, as shown in FIGS. 23 and 24, the second guide surface 66b is supported by the upper end 15a of the support member 15 when the input/output module 60 is placed at the second reference position. , may be formed on the outer surface of the hinge portion 64 to form a reference angle with the first guiding surface 66a.

Additionally, as shown in FIG. 22, the third guiding surface 66c is positioned at the upper end 15a of the support member 15 when the input/output module 60 is rotated between the first and second reference positions. It is supported by and may be provided to connect the first guide surface (66a) and the second guide surface (66b). This third guide surface 66c is preferably provided to continuously contact the upper end 15a of the support member 15 when the input/output module 60 is rotated between the first and second reference positions. . To this end, the third guiding surface 66c may have a curved shape with a predetermined curvature.

Meanwhile, as shown in FIG. 21, the support portion 13f has a first support protrusion 13j that protrudes toward the hinge portion 64, and the hinge portion 64 has a first support protrusion 13j that protrudes toward the support portion 13f. It may further have a second support protrusion (64g).

They are spaced apart from each other, but when the input/output module 60 is disposed at the second reference position, the second support protrusion 64g is supported by the first support protrusion 13j. In particular, the first support protrusion 13j and the second support protrusion 64g, when the input/output module 60 is rotated with a rotational force greater than or equal to a predetermined reference rotational force, the second support protrusion 64g moves the first support protrusion 13j. It is prepared so that you can ride on it. To this end, the first support protrusion 13j and the second support protrusion 64g may be provided to be elastically deformable.

Hereinafter, with reference to the drawings, a description will be given of how the input/output module 60 moves linearly in the height direction by the support member 15 and the guiding surface 66 when the input/output module 60 is rotated.

First, as shown in FIGS. 21 and 22, when the user holds the input/output module 60 placed at the first reference position and then rotates it in one predetermined direction toward the second reference position, the rotational force of the input/output module 60 and the first guide surface 66a presses the upper end 15a of the support member 15 in the downward direction of the housing main body 11 due to a load or the like. Then, the input/output module 60 and the hinge bracket 13 are rotated toward the second reference position, and at the same time, the housing is moved by a reaction force applied from the upper end 15a of the support member 15 to the first guiding surface 66a. The main body 11 is raised upward, and the first guide surface 66a slides along the upper end 15a of the support member 15 while being supported by the upper end 15a of the support member 15. .

In addition, as shown in FIG. 22, when the input/output module 60 is rotated by a predetermined angle or more from the first reference position, the third guiding surface 66c meets the upper end 15a of the support member 15, The input/output module 60 and the hinge bracket 13 are continuously raised toward the top of the housing body 11 by a reaction force acting from the upper end 15a of the support member 15 to the third guide surface 66c. As the input/output module 60 and the hinge bracket 13 are raised in this way, a portion of the hinge portion 64 and a portion of the hinge bracket 13 may be pulled out from the through hole 52c and exposed to the outside (FIG. 16 reference).

Thereafter, as shown in FIG. 24, when the input/output module 60 is rotated by a predetermined reference angle, the second guide surface 66b provided to form a reference angle with the first guide surface 66a is connected to the support member 15. ), and at the same time, the second engaging surface 64d of the hinge portion 64 is caught by the first engaging surface 13i of the hinge bracket 13. Then, the rotation and linear movement of the input/output module 60 is completed, and the input/output module 60 is connected to the discharge grill 52 with the second guide surface 66c supported by the upper end 15a of the support member 15. ) can be erected perpendicularly.

However, the second support protrusion 64g of the hinge portion 64 meets the bottom surface of the first support protrusion 13j when the rotation angle of the input/output module 60 approaches the reference angle. Then, the first support protrusion 13j and the second support protrusion 64g are elastically deformed by the rotational force of the input/output module 60, and through this, the second support protrusion 64g moves the first support protrusion 13j upward. You will ride in that direction. Accordingly, as shown in FIG. 24, when the input/output module 60 is rotated by the reference angle, the second support protrusion 64g is seated on the upper surface of the first support protrusion 13j. Then, the first support protrusion 13j supports the input/output module 60 through the second support protrusion 64g, thereby preventing the input/output module 60 from rotating backward toward the first reference position.

Referring to FIG. 25, when the input/output module 60 is placed at the second reference position, a force F0 applied from the hinge bracket 13 via the hinge pin 64b is applied to the input/output module 60, The load F1 of the module body 61, the reaction force F2 applied from the upper end 15a of the support member 15 to the second guide surface 66b, and the second support protrusion 64g Various external forces, such as the reaction force F3 applied to the support protrusion 13j, may be applied in combination. In addition, the force F0 applied from the hinge bracket 13 via the hinge pin 64b includes the load of the hinge bracket 13, the elastic force of the elastic member 17 applied to the hinge bracket 13, etc. can do.

In addition, the external forces F1, F2, and F3 each apply a rotational force (moment) centered on the hinge pin 64b to the input/output module 60, and when the sum of the applied rotational forces becomes '0', The input/output module 60 maintains its arrangement at the second reference position. Here, the rotational force acting on the input/output module 60 by each of the external forces (F1, F2, F3) is the size of each external force (F1, F2, F3), and the respective external forces (F1, F2, F3) This corresponds to the product of the distances (L1, L2, L3) between the applied point and the hinge pin (64b).

Meanwhile, the user applies a force (F4) to the input/output module 60 so that a rotational force greater than a predetermined reference rotational force is applied to the input/output module 60 in the other direction (counterclockwise in FIG. 25) centered on the hinge pin 64b. When applied, the first support protrusion (13j) and the second support protrusion (64g) are elastically deformed so that the second support protrusion (64g) passes over the first support protrusion (13j) in the downward direction, thereby forming the input/output module 60. It begins to rotate in the other direction. When the input/output module 60 is rotated in the above rotational direction, the hinge bracket 13 and the input/output module 60 are lowered toward the lower surface of the housing body 11 by the elastic force of the elastic member 17. Then, as shown in FIG. 21, the input/output module 60 has the support portion 13f supported by the bottom surface of the receiving groove 11m and the first guide surface 66a of the support member 15. It can be seated again in the seating groove 52a so as to be supported by the upper end 15a. Additionally, the hinge portion 64 and the hinge bracket 13 can be isolated from the outside by being inserted back into the through hole 52c.

As above, the air purifier 1 rotates the input/output module 60 by the interlocking action of the guiding surface 66 of the hinge portion 64 and the support member 15 of the housing 10. ), the hinge coupling structure of the input/output module 60 and the housing 10 is limitedly exposed to the outside only when the input/output module 60 is rotated by a reference angle so as to be separated from the seating groove 52a. Through this, the air purifier 1 can protect the hinged structure of the input/output module 60 and the housing 10 from the outside and improve aesthetics.
