Description

  The present invention relates to a vacuum cleaner, and more specifically to a vacuum cleaner.

  It can be said that the vacuum cleaner is a device that has a fan motor inside and filters dust after sucking air and dust from the outside. Such a vacuum cleaner can generally be referred to as a vacuum cleaner.

  The vacuum cleaner generally includes a canister type vacuum cleaner in which the main body and the suction nozzle are connected by an extension pipe or a connecting hose, and an upright type vacuum cleaner in which the suction nozzle is directly connected to the main body. is there.

  On the other hand, as a simple vacuum cleaner, many handy vacuum cleaners that can perform cleaning while the user directly holds the vacuum cleaner body are also widely used.

  In recent years, bedding vacuum cleaners that can clean bedding have become widespread with the improvement of living standards. Such a bedding vacuum cleaner can also be said to be a handy type vacuum cleaner, but unlike a general handy type vacuum cleaner, the bedding vacuum cleaner can include a vibration plate that applies vibration to the bedding.

  Handy vacuum cleaners are generally made to easily clean a portion of an object. Therefore, inconvenience due to the user's posture is not a big problem when handling a handy vacuum cleaner. The same applies to the canister type vacuum cleaner and the upright type vacuum cleaner. The reason is that when these are used, cleaning can be performed while the user is standing.

  However, when a user cleans bedding using a bedding vacuum cleaner, generally the entire bedding is cleaned uniformly over a long period of time. Therefore, inconvenience due to the user's posture during cleaning can be a problem.

  A conventional cleaner, particularly a bedding cleaner, will be described in detail with reference to FIGS.

  The bedding cleaner 1 can include an upper body 2, a handle 3, a nozzle body 5, and a lower body 4. The nozzle body 5 is provided horizontally with respect to the ground, particularly the bedding, and the bedding is cleaned through the nozzle body 5.

  The nozzle body 5 can be provided with a suction port 6 through which external air flows, a vibration plate 7 and an agitator 8. The vibration plate 7 performs a function of scattering dust in the bedding by applying vibration to the bedding, and the agitator 8 performs a function of sweeping dust on the surface of the bedding. Therefore, the operation of the vibration plate 7 and the agitator 8 makes the bedding cleaning more effective.

  The lower body 4 extends rearward from the nozzle body 5 substantially horizontally with respect to the ground. It can be said that the upper body 2 is joined to the upper part of the lower body 4 and the nozzle body 5 to form the main body of the vacuum cleaner.

  The lower body 4 is provided with a roller 9 for supporting the vacuum cleaner with respect to the ground. In essence, it can be said that the roller 9 and the agitator 8 support the vacuum cleaner on the ground or bedding.

  As shown in FIG. 3, the user cleans the bedding while grasping the handle 3 and running the cleaner back and forth.

  However, as illustrated, the conventional bedding cleaner has a problem that the height from the ground is low as a whole. Therefore, when cleaning the bedding, there is an inconvenience that the user needs to bend and clean for a long time.

  If the height of the bedding cleaner from the ground is low as a whole due to the characteristics of the bedding, a lot of friction and interference may occur between the bedding cleaner and the bedding. That is, the entire bottom surface of the bedding cleaner may be embedded in the bedding. This brings about the problem that not only the bedding part to be cleaned, but also the bedding part that has been cleaned is in close contact with the bottom surface of the bedding vacuum cleaner, thereby reducing the cleaning efficiency.

  In addition, due to the positional difference between the upper body 2 and the handle 3 of the vacuum cleaner, it is not easy to apply force to the ground or bedding. The user applies a force only to the front and rear during cleaning, and as a result, the nozzle body 5 may not be in close contact with the ground or bedding. Due to such problems, effective cleaning may not be performed. This is because vibration cannot be sufficiently applied to the bedding.

  In order to increase the height of the cleaner, the position of the handle 3 can be made higher. However, in this case, since the upper body 2 of the vacuum cleaner is formed long in the front-rear direction, the shape of the upper body 2 and the shape of the handle 3 can be imbalanced. As a result, there arises a problem that the overall appearance of the vacuum cleaner is not beautiful. The reason is that the handle 3 is excessively higher than the upper body 2 of the vacuum cleaner.

  In addition, the upper body 2 and the handle 3 are separately provided and connected to each other. Therefore, when the height of the handle 3 is increased, the overall outer shape is increased, which is inconvenient during handling and storage.

  On the other hand, the center of gravity of the vacuum cleaner is provided between the agitator 8 and the roller 9 for stable running. However, since the center of gravity of the vacuum cleaner is close to the ground, there is a problem in that the direction of the force applied to the handle 3 for traveling and the moment distance are increased. For this reason, as described above, the nozzle body 5 to be cleaned may not be in close contact with the ground or bedding.

  Since the lower body 4 and the nozzle body 5 are formed horizontally so as to correspond to the ground as a whole, traveling for cleaning is not easy. This is because an area unrelated to cleaning is close to the ground. On the contrary, such a shape means that it is not easy to increase the cleaning area, that is, the area of the nozzle body 5. As a result, for effective cleaning, there is a problem that the travel distance per hour has to be shortened. This eventually leads to the problem of long cleaning times.

  On the other hand, in the flow path inside the cleaner 1 shown in FIG. 3, there is a problem that the direction change frequently occurs and the air resistance is high.

  First, air flows into the dust box 12 via the air guide 11. In the air guide 11, the air is redirected to the upper part and the rear, and then redirected to the upper part again. The air flowing into the dust box 12 is discharged to the rear of the dust box and flows into the fan motor 13. The air that has flowed into the fan motor 13 is discharged to the outside via one side of the fan motor 13 (the direction of passage through the ground).

  With such a flow path structure, the direction of air flow frequently occurs until air flows into the vacuum cleaner and is discharged to the outside. As a result, there is a problem that noise increases and smooth cleaning is difficult. In addition, additional configurations for noise shielding can be added, and the structure of the fan motor chamber that houses the fan motor can be complicated.

  FIG. 4 shows a vibration system for driving the vibration plate 7 shown in FIG. 2 in a conventional cleaner. The vibration plate 7 may be applied to the bedding cleaner shown in FIGS.

  When the motor 14 rotates, the rotational force is transmitted to the reduction gear 16 via the belt 15. As a result, no vibration is generated by the rotation of the motor itself.

  Specifically, torque is improved through the belt 15, and vibration is generated by the eccentric bearing 17 after deceleration, and such vibration is connected to the vibration plate 7 through the connecting member 18. The connecting member 18 is elastically supported by the nozzle body 5 through the elastic member 19. As a result, there is a problem of having a complicated connection structure from the motor 14 to the vibration plate 7.

  In addition, vibration is transmitted to the belt 15, the reduction gear 16, and the motor 14, so that the durability of these structures is lowered, and there is a possibility that the positions of the respective components are fluctuated. For example, the motor is fixed inside the vacuum cleaner, but the fixed part may be broken or damaged by vibration.

  In addition, each of these connection structures can complicate the air flow path in the suction nozzle portion. In addition, the durability may be reduced due to the complicated and many configurations. Of course, since not only the motor fixing structure but also a structure for fixing the eccentric bearing 17 is added, there is a problem that the manufacturing becomes complicated.

  On the other hand, the vibration area becomes very narrow through the vibration mechanism and the vibration plate 7 shown in FIG. This means that the cleaning area is small. As a result, effective cleaning may not be performed.

  More specifically, the vibration plate 7 shown in FIG. 4 applies vibrations to the bedding alternately on the left and right. That is, when the left end of the vibration plate 7 is the lowermost position, the right end of the vibration plate 7 can be the uppermost position. As a result, there is a problem that vibration does not occur in the entire area of the vibration plate 7.

  Further, the amplitude amount is smaller at the center portion of the vibration plate than at the left end and the right end. This means that sufficient vibration cannot be applied to the bedding at the central portion of the vibration plate. Therefore, there is a need to provide a vibration mechanism or vibration plate that can effectively vibrate over the entire area of the vibration plate. There is a need to provide a vacuum cleaner having such a vibration mechanism or plate.

  As described above, the motor 14 and the reduction gear 16 are fixed to the internal structure of the vacuum cleaner. At this time, the internal structure is fixed to the main body inside the cleaner, but a lot of noise may be generated by vibration. For example, there may be a problem that screws and bolts continuously vibrate through vibrations with plastic injections (for example, fastening bosses and fastening holes). As a result, very unpleasant noise may occur.

  Therefore, there is a need to provide a cleaner having a vibration system that can be implemented more easily, has improved durability, reliability and vibration effects, and can significantly reduce the generation of noise.

  The present invention basically aims to solve the problems of the conventional vacuum cleaner described above.

  Through one embodiment of the present invention, it is intended to provide a vacuum cleaner having a vibration system that can be more easily implemented and has improved durability and reliability.

  Through one embodiment of the present invention, it is intended to provide a cleaner that allows air to flow more smoothly inside the cleaner, thereby improving cleaning efficiency and reducing noise.

  In order to achieve the above object, according to an embodiment of the present invention, in a vacuum cleaner having a suction nozzle part body forming a suction nozzle and a vibration system provided in the suction nozzle part body, the vibration system includes: A vacuum cleaner which is elastically supported by the elastic member with respect to the suction nozzle body can be provided.

  The vibration system may include a vibration plate that applies vibration to the object to be cleaned, and a vibration transmission member that transmits vibration generated by the motor to the vibration plate.

  Here, it is preferable that the vibration system does not come into contact with the suction nozzle body during vibration except for the elastic member. Specifically, in addition to the elastic support point through the elastic member, it is preferable that a support point for supporting the vibration system on the suction nozzle body is not formed. That is, it is preferable that the vibration system is fixed or supported with respect to the suction nozzle unit body only through the elastic support point.

  The suction nozzle body may be referred to as a first base body to be distinguished from various bodies constituting the vacuum cleaner.

  The vibration transmission member may include a connecting member that is provided on each of the left and right sides of the motor and connects the elastic member and the vibration plate.

  It is preferable that the connecting members are respectively extended forward and rearward from a central portion (hinge shaft) and then coupled to the elastic members. Therefore, two elastic support points can be formed through one connecting member. As a result, four elastic support points can be formed through the two connecting members. In other words, the vibration system can be elastically supported through four elastic support points by elastic members respectively provided on both the front and rear sides around the motor.

  The vibration plate may include a front vibration plate and a rear vibration plate that are individually provided.

  The front vibration plate may be elastically supported through elastic support points on both front sides, and the rear vibration plate may be elastically supported through elastic support points on both rear sides. Therefore, the front and rear and left and right vibration systems can be substantially symmetric through the four support points. Through this, the vibration system can be elastically supported more stably.

  It is preferable that the front vibration plate and the rear vibration plate vibrate up and down so as to cross each other. For this purpose, it is desirable that the motor is positioned such that the length direction (rotational axis direction) is the left-right direction of the cleaner.

  The vibration transmission member may include a motor housing portion that houses the motor, and the connection member may connect the motor housing portion and the vibration plate.

  The elastic member is provided to be fixed between the connecting member and the body, and the vertical amplitude of the vibration plate can be limited by the elastic force of the elastic member. That is, the shape and material of the elastic member can be selected so as to have an optimum amplitude.

  The motor is preferably a vibration motor that vibrates by rotation due to the eccentric load of the rotating shaft. As a result, vibration is directly generated by the rotation of the motor, so that each power transmission configuration for generating vibration can be omitted.

  The vibration plate has a bottom surface corresponding to the object to be cleaned, and a side surface extending upward from the bottom surface, and the vibration plate is visibly exposed to the outside of the cleaner through the side surface. Is desirable.

  A connection hole may be formed in the suction nozzle part body. Based on the connection hole, the upper part may be referred to as the upper part or the upper surface of the suction nozzle part body, and the lower part may be referred to as the lower part or the lower surface of the suction nozzle part body. The elastic member is preferably fixed to the fixing hole.

  The motor may be positioned on an upper surface of the suction nozzle unit body, and the connection member may be coupled to the elastic plate and the vibration plate positioned on the lower surface of the suction nozzle unit body through the connection hole. desirable.

  The elastic member may include a fixing part fixed to the connection hole and a connection part connected to the connection member.

  Preferably, the fixing part includes a flange part into which an upper part and a lower part of the edge of the connection hole are inserted, and the connection part includes a through hole through which the connection member penetrates radially inward of the flange part.

  In order to prevent the fixing part from being detached from the connection hole, a pressure member coupled to the suction nozzle part body to pressurize the fixing part may be provided.

  The connecting member includes a horizontal portion extending substantially horizontally from a central portion, a vertical portion extending substantially vertically downward from the horizontal portion and coupled to the vibration plate, and the horizontal portion and the vertical portion. An amplitude limiting rib may be included provided to limit the maximum downward displacement of the connecting member.

  The amplitude limiting rib may be positioned above the elastic member so as to pressurize the elastic member against the suction nozzle portion body when the downward displacement of the connecting member is greater than or equal to a predetermined value.

  The length of the amplitude limiting rib is preferably larger than the radius of the elastic member. Through this, the pressing area applied to the elastic member can be increased. In addition, it is possible to prevent the pressurization area applied to the elastic member from being reduced due to such a feature even in the case of the vertical amplitude decentered in the front-back direction or the left-right direction.

  In order to achieve the above-described object, according to an embodiment of the present invention, in a vacuum cleaner that sucks dust by applying vibration, the suction nozzle body forming the suction nozzle is provided inside the suction nozzle body, A motor that vibrates itself due to an eccentric load of the rotating shaft, a vibration plate that is provided outside the suction nozzle body and applies vibration to a cleaning object, a vibration transmission member that transmits vibration of the motor to the vibration plate, and A vacuum cleaner including an elastic member that elastically supports the motor, the vibration plate, and the vibration transmission member with respect to the suction nozzle portion body can be provided.

  The vibration plate may include a front vibration plate provided in front of the suction nozzle and a rear vibration plate provided separately from the front vibration plate behind the suction nozzle.

  In order to achieve the above-described object, a vacuum cleaner according to an embodiment of the present invention is a vacuum cleaner that sucks dust by applying vibration, and vibrates in a motor that vibrates by an eccentric load of a rotating shaft, and a cleaning object. It is possible to provide a vacuum cleaner that includes a vibration plate that adds a vibration and a vibration transmission member that transmits vibration of the motor to the vibration plate.

  The eccentric load can be realized by an eccentric weight connected to the rotating shaft. A force is generated in the tangential direction of the rotating circle by the rotation of the eccentric weight, and the motor itself vibrates by such a force.

  The vibration transmitting member may include a motor housing portion that houses the motor, and a connecting member that connects the motor housing portion and the vibration plate.

  The connecting member may be provided to transmit vibrations of the motor and the motor housing part to the vibration plate. Specifically, the coupling member converts the vibration of the motor and the motor housing part into a rotational motion with a limited rotation angle. To transmit to the vibrating plate. An elastic member can be provided to limit the rotation angle.

  Preferably, the motor housing part includes a hinge shaft, and the connecting member is rotatably connected to the hinge shaft.

  The connecting member is preferably formed to extend forward and backward from the hinge shaft.

  The connecting member may vibrate in a direction in which the front and rear intersect each other about the hinge axis.

  Preferably, the hinge shaft is provided at a lower portion from a rotation shaft of the motor. In addition, it is preferable that the hinge shaft is provided so as to be eccentric in the horizontal direction forward or backward of the rotation shaft of the motor.

  Due to the eccentric relationship between the rotating shaft of the motor and the hinge shaft, a rotational force is generated at the hinge shaft. In addition, the direction of the rotational force occurs alternately. As a result, such a rotational force results in rotation of the connecting member, which results in a vertical amplitude at the end of the connecting member.

  The hinge shaft may be provided on both sides (left and right) of the motor, and the connecting member may be provided for each of the hinge shafts.

  The two hinge shafts are coaxial, and separate vibration plates can be connected to the connecting member on both sides with respect to the hinge shaft. As a result, it is possible to apply vibration to the two vibration plates using one motor. In addition, the vibration system can be realized in a symmetrical form on both sides around the motor.

  Therefore, the vibration area can be increased, and the cleaning effect by vibration can be further enhanced. In addition, since the number of vibrations per hour can be increased by a factor of 2, the cleaning effect can be further enhanced.

  The elastic member is provided to be fixed between the connecting member and the body, and the vertical amplitude of the vibration plate can be limited by the elastic force of the elastic member.

  In order to achieve the above-described object, according to an embodiment of the present invention, in a vacuum cleaner having a suction nozzle portion that sucks dust by applying vibration to an object, the suction nozzle portion includes a suction nozzle. A vibration system having a body body and a motor that vibrates itself by an eccentric load of a rotating shaft, and a vibration plate that applies vibration to the object, the vibration system including the vibration plate with respect to a vibration direction of the vibration plate.

  It is desirable that the respective vibration plates vibrate in a crossing direction.

  The vibration system may include a motor housing portion, a hinge shaft provided in the motor housing portion, and a connecting member that extends in front of and behind the hinge shaft and is connected to the vibration plate.

  The hinge shafts are respectively provided on both sides (left and right) of the motor housing portion, and separate vibration plates can be coupled to the coupling member on the front and rear sides of the motor housing portion, respectively. Accordingly, the respective vibration plates can vibrate in the crossing direction.

  A hinge shaft fixing member for fixing the hinge shaft to the body may be provided. Through the hinge shaft fixing member, translational movement of the vibration motor and the motor housing portion can be restricted. The reason is that the force in such a direction, that is, the force for translational movement is converted into a rotational force at the hinge shaft. However, the hinge shaft fixing member can be omitted. This is because the translational movement of the vibration motor and the motor housing portion is limited through the elastic member. In this case, in the vibration system, a support point other than the support point through the elastic member may not be formed. That is, the entire vibration system is placed so as to be able to vibrate freely within a predetermined space through the elastic support point. In this case, since there is no hinge shaft fixing member, the translational width in the vertical direction becomes larger, and through this, the vibration width of the vibration plate can be increased.

  The motor housing part may include a motor placement part and a separation member that forms the hinge shaft so as to be separated from the motor placement part.

  The motor mounting part cover may be configured to cover the motor mounting part and to be separated from the motor mounting part.

  The vacuum cleaner may include a handle portion that is provided to allow a user to apply a force to operate the vacuum cleaner.

  In order to realize the above-described object, according to an embodiment of the present invention, a suction nozzle portion that is horizontally formed to correspond to the ground, and a fan motor mounting that is inclined and extended to the upper rear side of the suction nozzle portion. And a vacuum cleaner configured to include a body cover coupled to the suction nozzle portion and the fan motor mounting portion.

  A vibration motor is provided on the upper portion of the base body (first base body) corresponding to the suction nozzle portion, and a vibration plate for applying vibration generated by the vibration motor to the ground is provided on the lower portion of the first base body. be able to.

  A battery for applying power to the cleaner may be provided on the first base body. The vacuum cleaner may selectively implement a power connection type or a rechargeable type. Therefore, the battery mounting portion provided with the battery can be provided in a power source connection type or a rechargeable type. A rechargeable vacuum cleaner is implemented when a battery is placed on the battery placement unit, and a power-connected vacuum cleaner is implemented when a battery is not placed on the battery placement unit. In the latter case, it is necessary to provide a power cord for applying power separately.

  Here, it is preferable that the battery mounting portion is provided at an upper front portion of the first base body. Through this, the center of gravity of the vacuum cleaner can be positioned more forward.

  It is preferable that the base body (second base body) corresponding to the fan motor mounting portion is formed such that the height difference from the ground gradually increases toward the rear.

  It is desirable that the base body (second base body) corresponding to the fan motor mounting portion is provided with a fan motor so that the central axis thereof is in the oblique direction with respect to the ground. That is, it is desirable that the second base body in the oblique line direction is provided with a fan motor in the oblique line direction. Through this, it is possible to form channels substantially aligned in the oblique direction of the body.

  A support unit may be provided behind the suction nozzle unit and below the fan motor mounting unit and supports the cleaner together with the suction nozzle unit with respect to the ground.

  The center of gravity of the bedding cleaner is preferably located in front of the support portion. The support part preferably includes a support part bracket and a wheel provided on the support part bracket. The number of wheels may be one, but it is more preferable that two wheels are provided on both sides in consideration of the left and right center of gravity.

  The support bracket is preferably extended downward from the fan motor mounting portion in order to compensate for a height difference between the fan motor mounting portion and the ground. In order to minimize an area where the support bracket can come into contact with the ground, it is preferable that the support bracket is extended downward only at a part of the left and right widths of the base body. That is, it is preferable that the support bracket extend downwardly only at a part of the left and right center portion of the base body.

  It is preferable that the center of gravity of the fan motor provided in the fan motor mounting part is located in front of the wheel, and the center of gravity of the vacuum cleaner is located in an upper part of the fan motor mounting part perpendicular to the ground.

  A handle portion may be included that is provided for a user to apply force to operate the vacuum cleaner.

  In order to realize the above-described object, according to an embodiment of the present invention, a suction nozzle part that is horizontally formed to correspond to the ground, and extended from the upper part of the suction nozzle part to the upper rear side, A body formed so that a height difference from the ground gradually increases, a handle portion provided in the body so that a user applies force, a dust box attached to the body, provided in the body, A fan motor is provided at the rear of the dust box and provided to suck in air, and a flow path of air from the dust box to the fan motor is formed to be inclined rearward and upward from the inside of the body.

  The dust box can be mounted and separated in a direction substantially perpendicular to the inclination direction of the body.

  An air guide that guides the air flowing in from the suction nozzle part to the rear upper side and supplies the air to the dust box may be included. The air guide is preferably extended so as to be inclined rearward and upward from the suction port. Through this, a vibration motor may be located in the vertical upper part of the suction port.

  Since the suction port substantially forms the center of the suction nozzle portion, it is possible to easily balance the vibration plates respectively provided in front and rear of the suction nozzle portion. The reason is that a vibration motor is provided at the center of the suction nozzle, and the vibration system can be implemented so that the front and rear are symmetrical with respect to the vibration motor.

  The dust box communicates with the fan motor and communicates with a dust box discharge unit provided substantially perpendicular to the inclination direction of the body and the air guide, and is closer to the suction nozzle unit than the dust box discharge unit A dust box inflow portion provided at a more biased angle.

  The fan motor is preferably mounted such that a central axis is inclined with respect to the ground so as to correspond to the inclination of the body. Through this, an air flow path corresponding to the inclination of the body can be formed smoothly.

  It is preferable that the air flowing into the fan motor is discharged to the upper part of the fan motor and then discharged to both sides of the lower part of the body.

  It is desirable to include a support part provided behind the suction nozzle part and below the body and supporting the bedding cleaner together with the suction nozzle part with respect to the ground.

The vacuum cleaner comprised including a part can be provided. The suction nozzle part is preferably formed in a circular shape.

  It is desirable to include a handle portion provided on the rear upper part of the body so that a force applied by the user for traveling of the bedding cleaner is in a direction aligned with the inclination direction of the body.

It is the fragmentary sectional view which showed the elastic support structure and pressurization member structure of the vibration system in the cleaner shown in FIG.

  Hereinafter, a vacuum cleaner according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  First, with reference to FIGS. 5 to 7, the outer shape of the vacuum cleaner 200 applicable to one embodiment of the present invention will be described. In this specification, the left-right direction of the cleaner 200 shown in FIG. 5, that is, the traveling direction of the cleaner 200 can be defined as the front-rear direction. And the both-sides direction of the running direction of the cleaner 200 can be defined as the left-right direction.

  The vacuum cleaner 200 includes a body or a main body 20. That is, the main body 20 that forms the overall external shape of the vacuum cleaner is included. The main body 20 is preferably formed to be inclined with respect to the ground. That is, the center line S of the main body 20 is formed to be inclined rearward with respect to the ground. As a result, the height difference with respect to the ground becomes larger toward the rear of the main body 20.

  The angle α formed by the center line S and the ground is preferably 30 ° to 50 °, and more preferably about 40 °. The reason is that as the angle becomes larger, the center of gravity of the cleaner becomes excessively high, and conversely, as the angle becomes smaller, the same problem as in the conventional cleaner can occur.

  The vacuum cleaner 200 includes a suction nozzle portion 25 that is formed horizontally so as to correspond to the bedding placed horizontally with respect to the ground or the bed. That is, it can be said that the suction nozzle portion 25 corresponds to the cleaning region. Accordingly, the suction nozzle portion 25 forms a lower front portion of the main body 20. In other words, it is desirable that the main body 20 be extended from the upper portion of the suction nozzle portion 25 so as to be inclined rearward and upward.

  A lower portion of the main body 20 can be referred to as a base body 22. Accordingly, the front portion of the base body 22 can be referred to as the suction nozzle portion body or the first base body 23. In other words, the base body 22 corresponding to the suction nozzle portion 25 can be referred to as the first base body 23.

  The second base body 24 can be extended from the first base body 23 so as to be inclined rearward and upward. In other words, the front of the base body 22 can be referred to as a first base body 23, and the rear of the base body 22 can be referred to as a second base body 24.

  Therefore, the 1st base body 23 can be formed horizontally corresponding to the ground, and the 2nd base body 24 can be formed so that a height difference with the ground may become so large that it goes back. In addition, it is desirable that the inclination angle between the second base body 24 and the ground is substantially the same as the inclination angle α between the center line S of the main body 20 and the ground. The second base body 24 is desirably formed so as to continuously incline backward from the first base body 23.

  A support portion 70 for supporting the main body 20 with respect to the ground can be provided at the lower portion of the second base body 24. In addition, a handle portion 80 can be provided on the upper rear side of the main body 20.

  After grasping the handle portion 80, the user can apply a force so as to travel back and forth with the suction nozzle portion 25 in close contact with the bedding.

  On the other hand, the main body 20 can be configured to include a body cover 21 that forms an upper portion. The body cover 21 can be combined with the base body 22 to form an internal space. Various configurations to be described later can be located in such an internal space.

  FIG. 7 shows a separated state of the body cover 21 and the base body 22.

  The vacuum cleaner 200 may be configured to include a suction nozzle portion 25 that is formed horizontally so as to correspond to the ground, and a fan motor mounting portion 26 that is extended so as to incline to the rear upper side of the suction nozzle portion 25. it can.

  The suction nozzle portion 25 and the fan motor mounting portion 26 can be integrally formed to form a single base body 22.

  The base body 22 can be configured to include a first base body 23 corresponding to the suction nozzle part 25 and a second base body 24 corresponding to the fan motor mounting part 26. Therefore, it is desirable that the second base body 24 and the first base body 23 are integrally formed. The second base body 24 is preferably extended so as to incline toward the rear upper side of the first base body 23.

  A body cover 21 is provided on the upper portion of the base body 22, and an overall appearance of the vacuum cleaner can be formed by combining the two.

  The shape of the body cover 21 desirably matches the shape of the base body 22. Therefore, it is desirable that the body cover 21 is also formed so as to incline toward the rear upper part.

  The dust box 90 can be mounted through the inclined front surface of the body cover 21. Therefore, it is desirable that the mounting direction of the dust box 90 is substantially perpendicular to the inclination direction of the cleaner 200. Through this, a smoother air flow can be generated in the dust box 90 as will be described later.

  The first base body 23 is preferably provided with a vibration system 30. The vibration system 30 can include a vibration motor 31 and a vibration plate 32.

  A vibration motor 31 may be provided on the upper portion of the first base body 23, and a vibration plate 32 may be provided on the lower portion of the first base body 23. In other words, the suction nozzle unit 25 can include the vibration motor 31 and the vibration plate 32. The vibration directly generated through the rotation of the vibration motor 31 is transmitted to the vibration plate 32. The vibration plate 32 is positioned horizontally with respect to the ground or bedding and vibrates up and down. Accordingly, the vibration plate 32 sweeps dust by applying vibration to the bedding. The vibration system 30 will be described later in detail.

  On the other hand, a power cord 46 can be provided behind the second base body 24. Therefore, power for operating the vacuum cleaner can be supplied via the power cord 46.

  Since the vacuum cleaner 200 is suitable for a bedding cleaner, it can be said that the cleaning area corresponds to the area of the bedding. Therefore, unlike a general canister vacuum cleaner or an upright vacuum cleaner, it can be said that the cleaning area is relatively narrow. Therefore, the length of the power cord can be relatively shortened.

  The cleaner 200 according to the present embodiment can be selectively provided with a power cord 46 and a battery (not shown). That is, the power cord 46 can be eliminated and only the battery can be attached. This is because the battery can be charged when the cleaner 200 is attached to a charging station (not shown). Therefore, the charging method and the power connection method can be selectively configured in the same vacuum cleaner.

  A battery mounting portion 41 may be provided on the upper portion of the first base body 23 for mounting the battery. That is, a battery for applying power to the cleaner can be provided on the upper portion of the first base body 23. Of course, the battery mounting part 41 can be provided with both a charging method and a power source connection method without distinction for selective mounting of the battery.

  The battery is relatively heavy. Therefore, the position of the center of gravity of the entire cleaner 200 can be changed according to the mounting position of the battery.

  As above-mentioned, the vacuum cleaner which concerns on a present Example becomes large in height difference with the ground, so that it goes back. Therefore, it is necessary to move the center of gravity forward while lowering the center of gravity to ensure the convenience of travel.

  For this reason, it can be said that it is very effective to mount the battery on the upper portion of the first base body 23.

  In addition, the battery mounting portion 41 is more preferably located in front of the suction nozzle portion 25. Through this, the center of gravity of the cleaner 200 can be positioned more forward. Through such a battery mounting position, it is possible to further improve running stability.

  However, as will be described later, not a rechargeable vacuum cleaner but a power-connected vacuum cleaner can be provided. That is, it is possible to provide a vacuum cleaner that can perform cleaning only when the power cord 46 is connected to a power source. In this case, since the battery is not provided inside the main body 20, the center of gravity of the cleaner 200 moves to the rear of the main body 20 to some extent.

  Hereinafter, the center of gravity and the support structure of the vacuum cleaner that can be applied to one embodiment of the present invention will be described in detail with reference to FIGS. More specifically, the case of a power supply type cleaner will be described instead of a rechargeable cleaner (a cleaner having a battery).

  During cleaning, the body or main body 20 of the vacuum cleaner is substantially supported by the agitator 44. That is, the cleaner is supported with respect to the ground by the agitator 44 provided in the suction nozzle portion 25.

  However, the main body 20 is extended and formed so as to incline to the rear of the agitator 44, more specifically to the upper rear side. Therefore, it is desirable that a support portion 70 that supports the vacuum cleaner is provided behind the agitator 44.

  The support portion 70 is preferably provided at the rear of the suction nozzle portion 25 and the lower portion of the fan motor mounting portion 26. In other words, it is desirable that the support portion 70 be provided not on the first base body 23 but on the second base body 24. That is, the support point formed through the support part 70 is located in the lower part perpendicular to the ground in the second base body 24.

  Here, the center of gravity of the cleaner 200 is preferably located in front of the support portion 70. In addition, it is desirable that the center of gravity is located behind the suction nozzle portion 25. More specifically, it is desirable that the center of gravity of the cleaner 200 is positioned forward in the second base body 24 and the support point at a position perpendicular to the ground.

  Therefore, the cleaner 200 can be supported more stably by the relationship among the center of gravity of the cleaner 200, the position of the agitator 44, and the position of the support portion 70. And the running stability at the time of cleaning can be improved. Of course, the convenience of use can be further enhanced through this.

  The support part 70 preferably includes a support part bracket 71 and wheels 72. The wheel 72 can be rotatably fixed to the support bracket 71. It can be said that the wheel 72 and the agitator 44 form a support point that supports the cleaner 200 with respect to the ground.

  The support bracket 71 is preferably extended downward from the fan motor mounting portion 26 in order to compensate for the height difference between the fan motor mounting portion 26 and the ground. That is, it is desirable to extend from the lower part of the second base body 24 toward the ground.

  As shown in FIG. 6, the support bracket 71 extends downward from only a part of the left-right width of the second base body 24. The support bracket 71 is preferably extended downward from the left and right center of the second base body 24. This means that the area where the support bracket 71 can contact the ground is small.

  Therefore, it is possible to minimize the area that is not related to the cleaning area, that is, the area that can contact the ground and the bedding regardless of the cleaning.

  On the other hand, the wheels 72 can be provided on the left and right sides of the support bracket 71, respectively. The center of gravity of the vacuum cleaner can be located between the left and right wheels 72. As a result, it is possible to prevent the left and right from shaking when the cleaner is running. As a result, cleaning can be performed more stably.

  The wheel 72 is preferably bent upward by extending from the support bracket 71 to the left and right. In other words, the wheel 72 desirably has an elliptical cross section. This means that the area of the wheel 72 in contact with the ground or bedding is small.

  As an example, the shape of the wheel may be cylindrical. Such a cylindrical wheel has a relatively large area in contact with the ground or bedding. And when the bedding cleaner travels not only before and after the straight direction but also when the left and right curves are formed, it can often occur when the bedding cleaner moves forward and backward. Of course, depending on the mode of use, it is possible to move left and right ignoring the friction between the wheel and the bedding. However, in the case of a cylindrical wheel, a bedding phenomenon may occur when moving left and right.

  However, when the shape of the wheel 72 is formed in an elliptical shape, it is possible to remarkably reduce such a bedding entrainment phenomenon. The reason is that the area of the contact surface between the elliptical wheel and the bedding can be minimized.

  The cleaner 200 travels while applying force while the user holds the handle portion 80.

  As shown in FIG. 5, the handle portion 80 can be formed in a round shape. As a result, the handle portion 80 can be grasped conveniently, and the degree of wrist fatigue can be reduced.

  Specifically, the handle portion 80 is formed at the upper rear portion of the main body 20. The handle 80 is preferably formed integrally with the main body 20 for a beautiful design and easy handling. As an example, the handle portion 80 can be formed in a form in which a part of the main body 20 is penetrated.

  More specifically, the handle portion 80 can be formed in a form in which a part of the main body 20 penetrates so as to have a closed curve. In particular, the handle portion 80 can be provided in the body cover 21.

  Due to the shape and position of the handle portion 80, the user can apply a force 6 in the direction aligned with the inclination direction of the main body 20 for traveling. That is, for traveling forward, it is possible to easily apply force not only forward but also downward. This is because the force applied in the tilt direction is divided into a forward component and a downward component.

  The downward component of the force applied through the handle portion 80 means that the suction nozzle portion 25 is further brought into close contact with the ground. As a result, the cleaning effect can be further improved.

  Hereinafter, with reference to FIGS. 8 and 9, the flow path structure of the vacuum cleaner 200 that can be applied to one embodiment of the present invention will be described in detail.

  Air and dust flow into the cleaner 200 through the air guide 42 from the ground or bedding. The air guide 42 can be formed to incline backward with respect to the ground.

  The air guide 42 can be connected so as to communicate with the dust box 90. That is, the air guide 42 guides the air flowing in from the suction nozzle portion 25 to the upper rear side and supplies it to the dust box 90.

  The dust box 90 can be mounted and separated in a direction substantially perpendicular to the inclination direction of the main body 20.

  The dust box 90 includes a chamber 91 in which dust is accommodated, and may include a dust box inflow portion 94 into which dust flows and a dust box discharge portion 95 from which air is discharged.

  The dust box discharge unit 95 can be provided substantially perpendicular to the inclination direction of the main body 20. The dust box discharge part 95 can be formed in the mesh-shaped partition wall 93 in the form of a through hole. A filter 92 can be provided in front of the partition wall 93. Therefore, dust in the air is separated by the filter 92, and air can flow into the fan motor assembly 50 through the dust box discharge unit 95.

  The dust box inflow portion 94 communicates with the air guide 42. The dust box inflow portion 94 can be provided at an angle more biased toward the suction nozzle portion 25 than the dust box discharge portion 95. In other words, the dust box inflow portion 94 can be formed at an angle that is further horizontal to the ground.

  Due to the positional relationship among the air guide 42, the dust box inflow portion 94, and the dust box discharge portion 95, the air substantially flows in the backward inclined direction. In other words, it is possible to remarkably prevent the flow path direction from being changed to the left, right, up, down, and front and back.

  In addition, the air flow direction is substantially the same as the direction in which air flows into the fan motor assembly 50. As a result, inhalation can be performed very smoothly and air flow resistance can be minimized.

  The fan motor assembly 50 is preferably attached to the fan motor mounting portion 26. The fan motor mounting portion 26 can be provided in the second base body 24 formed to be inclined rearward. Therefore, it is desirable that the fan motor assembly 50 is also attached to the fan motor mounting portion 26 so as to be inclined rearward. That is, it is desirable that the central axis of the fan motor assembly 50 is substantially the same as the central line S of the main body 20.

  Depending on the mounting position of the fan motor assembly 50, it is possible to implement the same flow path direction that is substantially aligned with the center line S of the main body 20 within the main body 24. At the same time, depending on the mounting position of the fan motor assembly 50, the central axis of the fan motor 51 through which air flows is also inclined with respect to the ground.

  The air discharged from the dust box discharge unit 95 flows into the motor chambers 52 and 53 covering the fan motor 51 through the packing 55. The motor chambers 52 and 53 may include an upper motor chamber 52 and a lower motor chamber 53. Therefore, the upper motor chamber 52 and the lower motor chamber 53 are combined to form an internal space, and the fan motor 51 can be mounted in the internal space.

  The motor chambers 52 and 53 can perform a guide function for guiding the air flowing into the chamber in the discharge direction.

  A filter 54 may be provided on the upper motor chamber 52. In other words, the filter 54 can be provided to finally filter very fine dust inside the main body 20.

  The air discharged through the filter 54 moves downward from the left and right sides of the motor chambers 52 and 53 and can be discharged to the outside through the body discharge ports 45 provided on both sides of the first base body 23.

  Here, it can be seen that a sufficient space is secured between the main body 20, in particular, the inside of the body cover 21 and the outside of the motor chambers 52 and 53. Therefore, air can be discharged more smoothly. This is because air can be discharged by utilizing the side space of the body cover 21, and the flow rate of the discharged air can be reduced. Such a decrease in the flow velocity makes it possible to significantly reduce noise caused by the exhaust wind.

  For the reasons described above, the motor chambers 52 and 53 can be simplified. In other words, the noise shielding structure by the fan motor assembly 50 can be simplified or improved. That is, it is possible to configure a single chamber without forming a double motor chamber covering the fan motor 51. In the present embodiment, as described above, a single motor chamber can be configured by combining the upper motor chamber 52 and the lower motor chamber 53. This is because, as described above, the side space of the body cover 21 can be used to significantly reduce noise caused by exhaust air.

  As shown in FIG. 8, according to the embodiment of the present invention, it can be seen that the air flow path is formed to be inclined upward and rearward from the nozzle suction port 25 a (see FIG. 15) to the fan motor 51. . That is, it can be seen that the air flow path is formed substantially the same as the inclination direction of the main body 20. This means that the direction of the air flow path inside the main body 20 is not changed and is smooth.

  Specifically, in FIG. 8, white arrows indicate dust flow paths, and black arrows indicate air flow paths. Therefore, dust flows in the tilt direction to the dust box, and air flows in the tilt direction to the fan motor 51. In the fan motor 51, air can flow into the upper part through the lower part of the fan motor.

  On the other hand, as shown in FIG. 8, the relationship between the position of the wheel 72 and the center of gravity of the fan motor 51 is important. The fan motor 51 or the fan motor assembly 50 is relatively heavy. Therefore, the specific gravity which these weights occupy in the weight of the whole vacuum cleaner is large.

  It is desirable that the positions of the wheel 72 and the support bracket 71 are determined in consideration of the center of gravity of the fan motor 51 or the fan motor assembly 50. On the contrary, it is desirable to determine the mounting position of the fan motor assembly 50 in consideration of the positions of the wheel 72 and the support bracket 71.

  Specifically, the center of gravity of the fan motor assembly 50 is preferably located in front of a support point formed through the wheels 72 in order to improve running stability. Therefore, the center of gravity of the overall cleaner 200 can be easily positioned in front of the wheel 72 by the mounting position of the fan motor assembly 50. And as above-mentioned, when a battery is mounted | worn, the center of gravity of a cleaner can be located further ahead.

  However, regardless of the presence or absence of the battery, it is desirable that the center of gravity of the cleaner according to the present embodiment is located behind the suction nozzle portion 25 and in front of the support portion 70. In other words, it is desirable that the center of gravity of the vacuum cleaner 200 is provided at an upper portion perpendicular to the ground of the second base body 24 inclined to the rear upper portion. As a result, traveling stability can be ensured regardless of whether the vacuum cleaner is implemented in either a rechargeable type or a power source connected type.

  Hereinafter, with reference to FIG. 10 to FIG. 14, the vibration system 30 of the vacuum cleaner applicable to one embodiment of the present invention will be described in detail.

  First, the vibration generation and transmission mechanism will be described with reference to FIGS.

  In this embodiment, it is desirable that vibration is generated by the rotation of the vibration motor 31 itself. For this purpose, the eccentric weight 31 b can be connected to the rotating shaft 31 a of the vibration motor 31. As a result, the eccentric weight 31b is rotated by the rotation of the rotating shaft 31a, and the entire motor is vibrated by the rotation of the eccentric weight 31b. In other words, the motor itself vibrates due to the eccentric load of the rotating shaft 31a of the vibration motor 31. Therefore, vibration can be generated very simply and easily.

  The vibration of the motor itself can be transmitted to the vibration plate 32 via the vibration transmission member 33.

  The vibration transmission member 33 can include a motor housing portion 34 that houses the vibration motor 31, and a connecting member 35 that connects the motor housing portion 34 and the vibration plate 32.

  Specifically, the vibration transmitting member 33 or the motor housing portion 34 can be configured to include a center portion 36, and the connecting member 35 can be extended in the front-rear direction or the left-right direction with respect to the center portion 36. Referring to FIGS. 9 and 10, it can be seen that the connecting member 35 can extend before and after the cleaner 200. That is, the connecting member 35 can be connected to the vibration plate 32 after extending before and after the central portion 36 of the connecting member 35. The connecting member 35 may be symmetric with respect to the center portion 36. However, the connecting member 35 can be formed symmetrically on the left and right of the central portion 36 according to the position where the vibration motor 31 and the vibration transmission member 33 are provided.

  Moreover, the motor accommodating part 34 or the vibration transmission member 33 can be comprised including the separation member 33a. It can be said that the separating member 33a has a configuration in which the rotating shaft 31a of the motor and the central portion 36 are positioned so as to be separated from each other. That is, it can be said that the separation member 33a is configured to connect the motor mounting portion 34a on which the motor is mounted and the connecting member 35 to each other. In addition, as will be described later, the vibration motor 31 and the motor housing 34 may be configured to be positioned in space. In other words, the vibration motor 31 and the motor housing portion 34 may be separated from each other on the first base body 23.

  Such a separation member 33 a allows the vibration motor 31 and the motor housing portion 34 to vibrate in the space, and prevents such vibration from being directly transmitted to the first base body 23.

  As shown in FIG. 11, the entire vibration system 30 vibrates while the eccentric weight 31b rotates. For convenience of explanation, the left side direction can be referred to as an x-axis, the direction rising through the ground can be referred to as a y-axis, and the upward direction can be referred to as a z-axis with reference to the central portion 36 shown in FIG.

  The vibration generated in the vibration system 30 can be generated in all directions of the x-axis, the y-axis, and the z-axis. However, it can be said that the direction in which vibration is substantially applied to the bedding is the z-axis direction. Therefore, it is desirable to reduce the vibrations in the x-axis and y-axis directions because they are unrelated to bedding cleaning.

  Also, it is necessary to reduce the vibration in the z-axis direction so as to allow only a necessary vibration width. The reason is that if the vibration width is excessively large, the use can rather be very inconvenient.

  An elastic member 37 can be provided for vibration attenuation according to such a vibration direction. As will be described later, the elastic member 37 can significantly reduce unnecessary vibrations in the x-axis and y-axis directions and generate a stable vibration width in the necessary z-axis direction.

  Specifically, the vertical amplitude, that is, the amplitude in the z direction can be limited by the elastic member 37. In other words, the vertical amplitude of the connecting member 35 is limited by the elastic force of the elastic member 37. As a result, the elastic member 37 functions as a damper, allows only the amplitude of the connecting member 35 (for example, 3 mm to 4 mm), and prevents the generation of an amplitude larger than that.

  The vibration of the vibration motor 31 causes the front and rear of the connecting member 35 to vibrate in directions that intersect each other. That is, when an upward vibration displacement occurs on one side from the center, it can be said that a downward vibration displacement occurs on the other side from the center. It can be said that the downward vibration displacement is a displacement that directly applies an impact to the bedding.

  However, since the rotation of the motor is very fast, it can be substantially recognized that the user applies an impact simultaneously before and after the connecting member 35.

  On the other hand, according to the present embodiment, it is possible to provide a cleaner 200 that can vibrate two vibration plates using one vibration motor 31.

  As shown in FIG. 12, the center portion 36 and the connecting member 35 described above can be provided on both sides of the vibration motor 31.

  The two center portions 36 may be located on one straight line so that the centers are coaxial. Separate vibration plates can be provided before and after the central portion 36, respectively. In other words, separate vibration plates 32 can be provided on the front and rear sides with respect to the same axis formed by the respective central portions 36.

  Depending on the positional relationship between the vibration motor 31 and the vibration transmission member 33 and the shape of the vibration transmission member 33, the vibration direction of the connecting member 36 can cross back and forth as described above.

  That is, when the vibration plate 32 provided at the front moves to the lower part, the vibration plate 32 provided at the rear can move to the upper part. On the contrary, when the vibration plate 32 provided at the front moves to the upper part, the vibration plate 32 provided at the rear moves to the lower part. Therefore, vibrations can occur so as to cross each other at the front and rear of the suction nozzle portion 25.

  Due to the cross vibration between the two vibration plates 32, vibration is applied to a larger area, and the cleaning time can be significantly reduced. In addition, the number of times of applying vibration per time can be doubled. As a result, the cleaning efficiency can be remarkably increased.

  Below, with reference to FIG. 13 thru | or FIG. 15, the mounting structure of the vibration system 30 mentioned above is demonstrated in detail.

  First, as shown in FIG. 15, the suction nozzle portion 25 can be formed in a circular shape. In addition, a suction port 25 a that extends to the left and right can be formed in the lower central portion of the suction nozzle portion 25. That is, it can be said that the extending direction of the suction port 25a is substantially perpendicular to the traveling direction of the cleaner 200. In other words, the suction port 25a can be formed in a rectangle having a long left and right length and a short front and rear length.

  It can be said that the suction port 25a is formed by the air guide 42 described above. That is, one end of the air guide 42 can form the suction port 25a, and the other end can be formed to be inclined rearward and upward. Of course, the suction port 25 a can be connected to one end of the air guide 42.

  In addition, it is desirable that vibration plates 32 are respectively provided at the lower portion of the suction nozzle portion 25 and before and after the suction port 25a. Here, the outer shape of the vibration plate 32 desirably corresponds to the shape of the suction nozzle portion 25. That is, since the shape of the suction nozzle portion 25 can be circular, it is desirable that the outer shape of the vibration plate 32, that is, the edge shape is a semicircular shape. It is desirable that the two vibration plates 32 have a circular shape as a whole.

  As shown in FIG. 13, it is desirable that the vibration motor 31 is located substantially in the vertical upper part of the suction port 25a. That is, it is desirable that the length direction of the vibration motor 31 is a direction aligned with the length direction of the suction port 25a.

  2 and 4, it can be seen that in the conventional vibration system, the length direction of the motor 14 is perpendicular to the length direction of the suction port 6. In addition, it can be seen that the motor 14 is located behind the suction port 6. In addition, the vibration transmission mechanism between the motor 14 and the vibration plate 7 has a problem that the flow path structure from the suction port 6 to the dust box 12 is complicated. That is, as shown in FIG. 3, it can be seen that in the structure of the air guide 11, the air flow direction can only be changed frequently.

  However, according to the present embodiment, as shown in FIG. 13, since the vibration motor 31 is provided in the vertical upper part of the suction port 25a, the shape of the air guide 42 can be simply formed to be inclined backward. . The reason is that they do not interfere with each other due to the positional relationship between the motor accommodating portion 34 and the connecting member 35 and the air guide 42.

  Further, with such an arrangement, the vibration motor 31 can be positioned at the central portion of the first base body 23. Through this, it is possible to generate effective and uniform vibrations at the vibration plates 32 respectively positioned before and after the vibration motor 31.

  On the other hand, as described above, according to this embodiment, the vibration motor 31 itself vibrates, and the vibration transmission member 33 also vibrates. As a result, the motor housing portion 34 and the connecting member 35 also vibrate. That is, the entire vibration system 30 vibrates. Therefore, it is necessary to stably transmit the generated vibration to the vibration plate 32 while stably fixing the vibration system 30.

  First, it is necessary to protect the rotating motor from the outside. Therefore, a cover for protecting the motor at the upper part of the vibration motor 31 is necessary. Of course, since the vibration motor 31 is mounted on the motor mounting portion 34 a of the motor housing portion 34, the cover is desirably a motor housing portion cover 34 b that covers the motor housing portion 34.

  As described above, the vibration motor 31 vibrates by itself. As a result, when the motor housing portion cover 34b comes into direct contact with the vibration motor 31, the motor housing portion cover 34b vibrates and noise may be generated. Therefore, it is desirable that the motor housing cover 34b is positioned so as to be separated from the vibration motor.

  For this purpose, as shown in FIG. 14, the motor housing cover 34b is preferably coupled to the separation member 33a. In addition, it is desirable that the motor accommodating portion cover 34b is coupled to the separation member 33a so as to have a predetermined gap d.

  For this purpose, the separating member 33a can be provided with a boss 39 protruding upward. In addition, the bosses 39 can be formed in the front-rear direction along the length direction of the motor. The motor accommodating portion cover 34b can be coupled to the separation member 33a via a screw while being placed on the boss 39.

  Of course, an elastic member (not shown) is provided inside the motor housing cover 34b, and the contact noise between the vibration motor 31 and the motor housing cover 34b that can be generated can be minimized.

  As shown in FIG. 13, most of the configuration of the vibration system 30 is located above the first base body 23. Here, the vibration system 30 is preferably elastically supported by the first base body 23. The entire vibration system 30 is preferably elastically supported by the first base body 23 in order to effectively transmit vibration, maximize the vibration area, and reduce noise.

  Hereinafter, the elastic support structure of the vibration system 30, in particular, the elastic support structure of the vibration plate 32 will be described in detail with reference to FIGS. 16 to 18. In addition, the shape of the vibration plate 32 and the structure for protecting it will be described in detail.

  Through the above-described drawings, particularly FIGS. 5, 6 and 15, it can be seen that the vibration plate 32 can be exposed to the outside according to the embodiment of the present invention. That is, it can be seen that the user can visually confirm the vibration of the vibration plate 32 when cleaning the bedding through the cleaner 200.

  It can be said that the vibration plate 32 is configured to apply vibration to the bedding and to clean the bedding more effectively. Therefore, the user has a strong desire to visually confirm whether or not the vibration plate 32 applies vibration to the bedding. In other words, it is desirable that the vibration plate 32 can be exposed to the outside of the cleaner 200 to satisfy the user's visual and conceptual desires.

  As shown in FIGS. 1 and 2, in the conventional bedding cleaner, the vibration plate 7 is not exposed to the outside of the cleaner 1. As a result, the user confirms whether the vibration plate 7 is operating reliably, how much vibration is applied, and how much dust is scattered by the bedding by the vibration plate 7. There is a problem that it is difficult.

  In order to solve such a problem, in this embodiment, it is possible to provide a cleaner provided with the vibration plate 32 so as to be visibly exposed to the outside at the operating position of the cleaner. As a result, the form in which the vibration plate 32 applies vibration to the bedding can be visualized, and the reliability for cleaning can be improved.

  Therefore, the suction nozzle portion 25 of the vacuum cleaner can be formed in a circular shape, and the vibration plate 32 can be formed in a circular shape or a semicircular shape corresponding to the outer shape of the suction nozzle portion 25. That is, the outer shape of the vibration plate 32 can be formed to correspond to the outer shape of the first base body 23.

  However, since the vibration plate 32 is configured to vibrate, the vibration plate 32 must be connected to the first base body 23 so as to vibrate. Further, the vibration plate 32 may be damaged due to contact with a hard object that is not bedding during cleaning. Therefore, it is desirable that it can be exposed to the outside while allowing vibrations and can avoid contact with a hard object excluding the bottom bedding as much as possible.

  For this reason, as shown in FIG. 16, it is desirable that the vibration plate 32 has a bottom surface portion 32b and a side surface portion 32a. The side surface portion 32a can be formed to have a height greater than the thickness of the bottom surface portion 32b. Accordingly, the side surface portion 32 a can be substantially exposed to the outside of the cleaner 200.

  When cleaning the bed matrix or bedding on the bed, the vacuum cleaner 200 may hit the bedside chest, bed headboard or wall surface. In this case, noise is generated when the vibrating plate hits the bedside chest, the bed head board, or the wall surface, and breakage due to impact can occur. In addition, when the vacuum cleaner falls, an impact is directly applied to the vibration plate 32. As a result, when the vibration plate 32 is exposed to the outside, the vibration plate 32 may be damaged, removed, broken, and deformed.

  As shown in FIG. 16, the outermost contour of the vibration plate 32 is preferably located inside the suction nozzle portion 25 or the first base body 23. When the suction nozzle portion 25 is circular, it is desirable that the side surface portion 32a is located a predetermined distance away from the outermost contour of the suction nozzle portion 25 inward in the radial direction. As a result, the vibration plate 32 can be prevented from hitting the wall surface during cleaning. That is, not the vibration plate 32 but the first base body 23, the main body 20, or the body cover 21 comes into direct contact with the wall surface or the like.

  Therefore, it is desirable that the vibration plate 32, in particular, the side surface portion 32 a of the vibration plate forming the edge, be located inward by a predetermined distance with respect to the entire edge of the suction nozzle portion 25. In other words, when the suction nozzle portion 25 is circular, it is desirable that the maximum radius of the vibration plate is smaller than the maximum radius of the suction nozzle portion. Of course, even if the suction nozzle portion 25 has various shapes such as a polygon, it can be said that the vibration plate is pulled in a predetermined length radially inward.

  On the other hand, since the vibration plate 32 vibrates up and down, it is necessary to prevent contact with the first base body 23 during vibration.

  The suction nozzle part body or the first base body 23 may include an upper vertical outer wall. It can be said that the upper vertical outer wall 23 a substantially forms the outermost wall of the suction nozzle portion 25. Since the vertical outer wall 23a can be in direct contact with the external wall surface, the vibration plate 32 can be protected.

  The first base body 23 includes a lower vertical outer wall 23b positioned so as to be drawn inward in the radial direction in order to avoid interference due to vertical vibration of the vibration plate 32, particularly the side surface portion 32a, below the upper vertical outer wall 23a. Can be included. In other words, it can be said that the uppermost end of the side surface portion 32a is located between the upper vertical outer wall 23a and the lower vertical outer wall 23b. In addition, a horizontal wall 23d can be formed between the upper vertical outer wall 23a and the lower vertical outer wall 23b. In other words, it can be said that the lower vertical outer wall 23b is positioned radially inward of the first base body 23 by the distance of the horizontal wall 23d.

  The uppermost end of the side surface portion 32a and the horizontal wall 23d are separated by a predetermined distance. That is, it is desirable that the predetermined distance is larger than the allowable vibration width of the vibration plate 32. As a result, it is possible to prevent the vibration plate 32 from contacting the first base body 23 under normal vibration conditions of the vibration plate 32.

  On the other hand, it is desirable that a curved surface portion 32 c be provided between the bottom surface portion 32 b and the side surface portion 32 a of the vibration plate 32. That is, the bottom surface portion 32b can be formed integrally with the side surface portion 32a through the curved surface portion 32c. Since the curved surface portion 32c can be formed in a round shape, the area that receives an impact from the outside can be increased. As a result, the impact can be reduced.

  Further, the side surface portion 32a is desirably formed so as to expand outward in the radial direction as it goes upward. In other words, it is desirable that the radius at the uppermost end of the side surface portion 32a is maximized. This minimizes the exposure distance of the entire side surface portion 32a (the distance between the side surface portion 32a and the outermost contour of the first base body) at the same time that the side surface portion 32a is visibly exposed to the outside as much as possible. Because.

  As described above, the vibration plate 32 is elastically supported by the first base body 23 by the elastic member 37. The elastic member 37 determines the vibration width of the vibration plate 32 and simultaneously performs a function of absorbing an external impact applied to the vibration plate 32. For example, when the vacuum cleaner falls while it is not operating, an external impact is applied to the vibration plate 32. At this time, the elastic member 37 can absorb many impacts.

  However, such an external impact may cause the vibration plate 32 to move beyond an allowable separation distance. For example, when the vibration at the time of cleaning is 3 mm to 4 mm, the vibration plate 32 can move more than the allowable separation distance up and down or front and back by an external impact.

  At this time, the vibration plate 32 may be detached from the connecting member 35 and the elastic member 37 described above. In addition, such an external impact may cause damage or deformation of the vibration plate 32.

  In order to eliminate such a fear, first, the horizontal portion 23d described above restricts an excessive rise of the vibration plate 32. Further, in order to prevent the vibration plate 32 from moving excessively inward in the radial direction, a reinforcing rib 23c can be provided.

  The reinforcing rib 23 c can be positioned so as to correspond to the side surface portion 32 a of the vibration plate 32. That is, in order to prevent the vibration plate 32 from moving excessively inward in the radial direction, the reinforcing rib 23c can be provided.

  The reinforcing rib 23c may be located at the lower part of the lower vertical outer wall 23b. And it can be provided so as to extend from the radially inner side of the lower vertical outer wall 23b to the lower part. Therefore, when the side surface portion 32a of the vibration plate 32 moves excessively inward in the radial direction due to external impact, the side surface portion 32a comes into contact with the reinforcing rib 23c.

  Therefore, a strong external impact can be transmitted to the more rigid first base body via the reinforcing rib 23c. That is, it is possible to absorb a strong external impact and prevent the vibration plate from being damaged.

  Below, with reference to FIG.17 and FIG.18, the elastic member 37 mentioned above and the elastic support structure of the vibration system 30 through this are demonstrated in detail.

  The first base body 23 can be provided with a connection hole 47. It can be said that the upper part and the lower part of the first base body 23 communicate with each other through the connection hole 47. That is, it can be said that the upper vibration is transmitted to the lower vibration plate 32 through the connection hole 47.

  Specifically, the connecting member 35 passes through the connecting hole 47 and is connected to the lower portion of the suction nozzle portion 25. The vibration plate 32 is connected to the end of the connecting member 35. Here, in order to elastically support the connecting member 35 and the vibration plate 32, the connecting hole 47 may be provided with an elastic member 37.

  Therefore, as shown in FIG. 12, a total of four support points, two on the front sides and two on the rear sides, can be formed around the motor. In addition, the two front elastic support points can be connected to the front vibration plate, and the two rear elastic support points can be connected to the rear vibration plate. Through such a connection structure, the front vibration plate and the rear vibration plate vibrate up and down while crossing each other due to the vibration of the motor.

  A part of the elastic member 37 can be fixed to the connection hole 47, and the other part can be connected to the connection member 35. Due to the elastic characteristics of the elastic member 37 itself, the elastic member 37 can be elastically deformed by the vibration of the connecting member 35. Such elastic deformation means the vibration of the connecting member 35, which can be said to mean the vibration of the vibration plate 32.

  Specifically, the elastic member 37 may include a flange portion 37 a that is fixed to the edge of the connection hole 47. As shown in FIG. 18, the flange portion 37 a is inserted into the upper portion and the lower portion of the edge of the connection hole 47, respectively. Therefore, it can be said that the elastic member 37 is fixed to the first base body 23 through the flange portion 37a.

  A through hole 37 b can be formed in the radial direction inner side of the flange portion 37 a, that is, in the center portion of the elastic member 37. The through-hole 37b has a predetermined height and can be formed so that the inner diameter is variable in a wrinkle shape.

  The connecting member 35 can penetrate the through hole 37b. Therefore, the connecting member 35 can be elastically supported by the first base body 23 by fixing the connecting member 35 to the through hole 37b. Then, the vibration plate 32 can be coupled to the end through which the connecting member 35 penetrates. Therefore, the vibration plate 32 can also be elastically supported by the first base body 23 through the connecting member 35.

  Therefore, as described above, the shape and the fixing structure of the elastic member 37 can significantly reduce the x-axis and y-axis vibrations. In addition, it can be said that the elastic member 37 is always present in the x and y axis vibration displacement. Therefore, the x-axis and y-axis vibrations can be reduced and the impact can be reduced.

  The elastic member 37 may include an extension portion 37c between the flange portion 37a and the through hole 37b. The flange portion 37a is fixed to the first base body 23, and the through hole 37b moves up and down by vibration. Therefore, it can be said that the extension part 37c is a part which applies elastic force substantially. Therefore, it is desirable that the extension portion 37c be formed in a diaphragm shape. Through this, while restricting the vertical movement width of the connecting member 35 and the vibration plate 32, it is possible to absorb external impact applied to the vibration plate 32. In other words, it is possible to form a constant z-axis vibration width by such a shape and fixing structure of the elastic member 37.

  However, the vibration plate 32 may move excessively due to external impact, and as a result, the elastic member 37 may be detached from the first base body 23. In particular, the elastic member 37 may be detached from the through hole 37b. The reason is that the displacement of the vibration plate 32 can be greatly generated in the z-axis direction due to the user's carelessness such as dropping of the cleaner or excessively pushing the vibration plate 32 upward or pulling the vibration plate 32 downward.

  As shown in FIG. 17, the pressure member 49 can be coupled to the upper portion of the first base body 23. That is, the first base body 23 can be provided with the pressure member 49 for making the coupling between the elastic member 37 and the through hole 37b more firm.

  Specifically, as illustrated in FIG. 18, the pressing member 49 can be provided to pressurize the flange portion 37 a of the elastic member 37. The flange portion 37 a is further in close contact with the through hole 37 b through the pressure member 49. At the same time, when the flange portion 37a moves inward in the radial direction and tries to leave the through hole 37b, such a movement is restrained by the pressing member 49. The reason is that the radial movement of the flange portion 37a is limited by the force applied in the vertical direction. Therefore, the elastic member 37 can be firmly coupled to the first base body 23. This means that the vibration system 30 is elastically supported on the first base body 23 by an external impact.

  On the other hand, the pressurizing member 49 can be provided so as to pressurize the upper part or the lower part of the flange part 37a, and can be provided so as to pressurize only one side. 17 and 18 show an example in which only the upper part is pressurized. In addition, the pressurizing member 49 can pressurize the flange portion 37a as a whole along the circumferential direction of the flange portion 37a. However, the connecting member 35 must be connected to the through hole 37b from the vibration motor 31 through a part of the flange portion 37a. Therefore, as shown in FIG. 17, the pressurizing member can be provided so as to pressurize the flange portion 37a only at the portion excluding the extension path of the connecting member.

  In addition, it is desirable that the pressure member 49 is coupled to the suction nozzle portion body or the first base body 23 independently of the elastic member 37. In other words, the pressure member 49 and the first base body 23 can be coupled via a separate coupling means (for example, using a screw not shown). Such a coupling means has nothing to do with the vibration system 30. As a result, the coupling between the two can be robust despite vibration. Accordingly, the pressure applied from the pressure member 49 to the elastic member 37 does not change in spite of vibration. Therefore, it is possible to effectively prevent the elastic member 37 from being detached from the first base body 23.

  Hereinafter, the positional relationship between the vibration transmitting member 33 and the first base body 23 and the structure for preventing the elastic member 37 from being detached will be described in more detail with reference to FIGS. 11 and 18.

  A vibration system 30 is provided on the first base body 23, particularly on the upper portion of the first base body 23. The vibration motor 31 can be damaged when it collides with an external structure during vibration. Of course, the external structure may be damaged. Such an external structure may be the first base body 23. Therefore, it is desirable that the vibration motor 31 does not interfere with the first base body 23. For this, the vibration transmission member 33 may include a separation member 33a.

  Such a separating member 33a performs a function of separating the vibration motor 31 from the upper portion of the first base body 23 by a predetermined distance or more.

  On the other hand, the vibration transmitting member 33 has a central portion 36 for longitudinal vibration. The connecting member 35 can extend back and forth from the center. Of course, it is desirable that the central portion 36 is also located on the first base body 23 and does not come into contact with the first base body 23 during vibration.

  In order to transmit the vibration to the vibration plate 32, the connecting member 35 is extended from the central portion 36 to the front and rear substantially horizontally and from the horizontal portion 35a substantially vertically downward. And a vertical portion 35b.

  The vertical portion 35 b can be connected to the vibration plate 32 through the connection hole 47. Of course, it can be said that the vertical portion 35 b is coupled to the elastic member 37 through the connection hole 47.

  An amplitude limiting rib 35c can be formed between the horizontal portion 35a and the vertical portion 35b. Such an amplitude limiting rib 35c may be for reinforcing the rigidity of the connecting member 35 first. However, the amplitude limiting rib 35c can be provided so as to limit the distance at which the connecting member 35 is particularly spaced downward in the z direction.

  The vibration width at the time of cleaning is manufactured to have a predetermined vibration width, and may be 3 mm to 4 mm as an example. Therefore, the position of the connecting member 35, particularly the horizontal portion 35 a, must be separated from the upper surface of the first base body 23 to the upper side by a larger amount than the predetermined vibration width. However, the amplitude limiting rib 35c can extend downward from the horizontal portion 35a near the vertical portion 35b or near the connecting hole 47.

  Here, it is desirable that the amplitude limiting rib 35c be spaced apart from the upper surface of the first base body 23 to be larger than the predetermined vibration width. As a result, the amplitude limiting rib 35c does not contact the first base body 23 during general vibration cleaning.

  The user may carelessly pull the vibration plate 32 downward. At this time, the amplitude limiting rib 35c prevents an excessive downward separation of the connecting member 35. The reason is that the amplitude limiting rib 35 c comes into contact with the upper surface of the first base body 23 when the connecting member 35 is displaced downward by a certain width from the predetermined vibration width. As a result, no further downward displacement of the connecting member 35 occurs.

  However, when there is no amplitude limiting rib 35c, the downward displacement of the connecting member 35 can be larger. Such a large downward displacement means that the downward displacement of the elastic member 37 is large. As a result, the possibility that the elastic member 37 is detached from the first base body 23 is increased. Therefore, the possibility of detachment of the elastic member 37 can be significantly reduced through the amplitude limiting rib 35c.

  This will be described briefly below.

  For example, it can be assumed that the elastic member 37 is detached from the first base body 23 when a downward displacement of 15 mm occurs. When a downward displacement of 10 mm occurs in the connecting member 35, no further downward displacement occurs in the connecting member 35 through the amplitude limiting rib 35c. As a result, the force required for the additional 5 mm downward displacement is significantly greater than the force required for the 10 mm downward displacement. That is, since the continuity of the force rising at a constant ratio is broken, the possibility of the elastic member 37 being detached can be reduced. On the other hand, when there is no amplitude limiting rib 35c, the continuity of the force is maintained, so that the elastic member 37 can be detached relatively easily.

  On the other hand, as shown in FIGS. 11 and 18, the amplitude limiting rib 35 c is located on the elastic member 37. The amplitude limiting rib 35 c can be formed in a form having a radius larger than that of the elastic member 37 around the connection hole 47.

  Therefore, as described above, when a downward displacement of 10 mm occurs in the connecting member 35, the amplitude limiting rib 35c comes into contact with the elastic member 37. Then, as the downward displacement becomes larger, the elastic member 37 is further pressed against the first base body 23. That is, the pressing force of the elastic member 37 through the amplitude limiting rib 35c is further increased. As a result, the possibility of detachment of the elastic member 37 is further reduced. Of course, such an amplitude limiting rib 35c can be provided in combination with the pressure member 49 described above.

  Hereinafter, the elastic support structure of the vibration system 30 will be described in more detail with reference to FIGS. 11 to 13.

  With the first base body 23 as a boundary, each component (motor, vibration transmission member) that generates and transmits vibration is positioned at the upper portion, and a vibration plate 32 that transmits vibration to the outside is positioned at the lower portion. To do. Specifically, it can be said that the vertical portion 35 b of the extension member 35 penetrates the first base body 23 and is connected to the vibration plate 32.

  Here, it can be said that the first base body 23 is provided with an elastic member 37, and as a result, the above-described characteristics appear with the elastic member as a boundary.

  Each component of the vibration system 30 is displaced by vibration. On the other hand, it can be said that the first base body 23 has a relatively fixed configuration. The reason for this is that the vibration and displacement transmitted to the first base body 23 via the elastic member are relatively small compared to the vibration and displacement of the vibration system 30.

  Therefore, due to such vibration and displacement characteristics, the contact between the vibration system 30 and the first base body 23 can induce tremor noise.

  According to the present embodiment, it is desirable that the vibration system 30 is elastically supported by the first base body 23 by the elastic member 37. The entire vibration system 30 is preferably supported so as to vibrate with respect to the first base body 23 through the elastic member 37.

  Therefore, except for the elastic member 37, the contact between the vibration system 30 and the first base body 23, and in general, other fixed structures is cut off, so that noise generation can be significantly reduced.

  In addition, a uniform amplitude is generated over the entire bottom surface of the vibration plate 32 through such an elastic support structure. As a result, the vibration area, that is, the cleaning area can be increased, and uniform and effective cleaning can be performed over the entire cleaning area.
