Description

  The present invention relates to a vacuum cleaner.

  In general, a vacuum cleaner is a device that filters dust and foreign matter inside the main body after sucking in dust and foreign matter existing on the surface to be cleaned by using a suction motor provided inside the main body.

  The vacuum cleaner as described above includes an up-right type vacuum cleaner in which a suction nozzle is connected to the main body and moves together with the main body, and the suction nozzle is connected to the main body by an extension pipe, a handle, a hose or the like. A canister type vacuum cleaner can be distinguished.

  Prior art Korean published patent publication No. 10-2012-0004100 (publication date: Jan. 12, 2012) discloses contents relating to a canister type vacuum cleaner.

  The conventional vacuum cleaner disclosed in the prior document includes a suction motor that is provided in a main body and generates suction force, a dust separation device that separates dust and air sucked by the suction force of the suction motor, and the dust It includes a dust collection container in which the garbage separated by the separation device is collected.

  The air containing the dust flows into the inflow pipe provided in the main body through the suction nozzle and the connecting portion by the suction force of the suction motor. The air is sucked into the dust separator through the inflow pipe. The air sucked into the dust separator is separated in the process of flowing through the dust separator. The dust separated by the dust separation device is collected in the dust collecting container through a dust discharge portion.

  On the other hand, the inflow pipe extends upward from the lower part of the dust separator and the dust collecting container toward the inlet of the dust separator inside the main body (see FIG. 3 of the prior document). With such a structure, the conventional vacuum cleaner generates a flow loss due to friction while the sucked air flows through the inflow pipe. For this reason, there is a problem that the amount of air flowing into the dust separation device is reduced, and the suction force of the vacuum cleaner is reduced.

Since the cover member is in pressure contact when the cover member is closed, the first sealing portion and the second sealing portion flow into the suction port through the connector. Air can be prevented from leaking, and the suction performance of the vacuum cleaner can be improved.

  In addition, since the sealing member is provided between the connector and the suction port of the dust collection box, airtightness between the connector and the dust collection box can be ensured.

  Further, since the distance between the end of the suction hose and the suction port of the dust collection box is formed to be relatively short, it is advantageous for securing the space inside the cleaner body.

  Moreover, since the suction hose, the connector, and the suction port are aligned on the same extension line, the flow resistance can be minimized when the air discharged from the suction hose flows to the suction port.

  Also, the end of the suction hose is inserted inside the connector and extended to a position adjacent to the suction port, so that the air discharged from the suction hose effectively flows into the suction port. There is.

  In the vacuum cleaner of the present invention, when the battery is separated from the main body, the center of gravity is located forward and rotates forward, so that the battery can be easily coupled to the cleaner main body.

  Moreover, since the cleaner body is supported at two points by a pair of moving wheels, it can easily move over obstacles such as thick carpets and futons.

  Moreover, since the mounting position of the battery is located on the lower side of the cleaner body, the center of gravity of the cleaner body can move downward and the running stability of the cleaner body can be improved.

  Moreover, since a support part is provided in the back of a main-body part, it can prevent that a main-body part falls backward.

  Referring to FIGS. 2 and 3, the cleaner body 10 may include a connector 134 connected to the suction device 20. The connector 134 is directly connected to the suction hose 23 so that air containing dust can flow in. That is, the connector 134 has one side coupled to the suction hose 23 and the other side coupled to the suction port 124. Accordingly, the connector 134 connects the suction hose 23 and the suction port 124.

  The connector 134 can communicate with the dust collection box 120. As a result, the air flowing into the suction hose 23 can flow into the dust collection box 120 through the connector 134.

  A suction port 124 through which dust flows can be provided on one side of the dust collection box 120. The suction port 124 may be provided in the upper part (or the upper surface part) of the dust collection box 120 as illustrated.

  In addition, the suction port 124 may be formed to face forward. Here, the front indicates a portion where the suction hose 23 is located with reference to the cleaner body 10.

  Further, as shown in the figure, the connector 134 may be disposed on the dust collection box 120. By arranging both the suction port 124 and the connector 134 above the dust collection box 120, the flow path length of the air flowing from the suction hose 23 can be minimized.

  The suction hose 23 may be provided with fitting parts 231, 232, and 233 for improving airtightness when coupled to the connector 134.

  The fitting parts 231, 232, and 233 can attach and detach the suction hose 23 to the connector 134. The fitting parts 231, 232 and 233 may be formed in multiple stages as shown.

  The fitting parts 231, 232 and 233 may include a first fitting part 231, a second fitting part 232, and a third fitting part 233. The first fitting part 231 and the second fitting part 232 are inserted into the connector 134. Accordingly, the first fitting portion 231 and the second fitting portion 232 are collectively referred to as an insertion portion, and can be referred to as a first insertion portion and a second insertion portion, respectively. The third fitting part 233 is provided outside the connector 134. The third fitting part 233 may be in contact with the end of the connector 134 to limit the insertion depth of the insertion part.

  The vacuum cleaner body 10 further includes a cover member 130 that is movably provided on the main body 110.

  The cleaner body 10 may further include a connecting member 13 that connects the cover member 130 and the main body 110. For example, the cover member 130 may be rotatably connected to the main body 110 by the connecting member 13.

  The cover member 130 may be provided with the connector 134. Accordingly, the connector 134 can move together with the cover member 130.

  The cover member 130 may shield at least one side of the dust collection box 120. The cover member 130 may be coupled to the dust collection box 120 at the same time as shielding at least one side of the dust collection box 120. When the cover member 130 is closed, it is coupled to the dust collection box 120, and when the cover member 130 is opened, it can be separated from the dust collection box 120.

  For example, the cover member 130 may be coupled to the upper part of the dust collection box 120.

  The dust collection box 120 can be separated from the main body 110 as shown in FIG.

  The main body 110 may be provided with a seating portion 108 on which the dust collection box 120 is seated. The seating part 108 may be disposed under the dust collection box 120 as illustrated. The seating part 108 may be formed with a coupling part (not shown) for coupling with the bottom part of the dust collection box 120.

  Meanwhile, the bottom surface of the dust collection box 120 may be referred to as one side of the dust collection box 120, and the top surface of the dust collection box 120 may be referred to as the other side of the dust collection box 120. Since the cover member 130 is coupled to the dust collection box 120 on the upper side of the dust collection box 120, it can be said that the cover member 130 is provided on the side opposite to the seating portion 108.

  Hereinafter, a state where the cover member 130 is opened and a state where the cover member 130 is closed will be described in detail.

  4 is a perspective view of the cleaner body when the cover member is opened, FIG. 5 is a longitudinal sectional view of FIG. 4, and FIG. 6 is a perspective view of the cleaner body when the cover member is closed. FIG. 7 is a longitudinal sectional view of FIG.

  4 to 7, when opening the cover member 130, the user can hold the grip portion 104 and lift the cover member 130 upward or rotate it backward. Conversely, when closing the cover member 140, the user can lower the cover member 130 downward or rotate it forward.

  When the cover member 130 is open, the user can pull out the dust collection box 120 to the outside. At this time, the suction port 124 of the dust collection box 120 is exposed to the outside.

  When the cover member 130 is closed, at least one side of the dust collection box 120 is shielded by the cover member 130. When one side of the dust collection box 120 is shielded by the cover member 130, the suction port 124 is also shielded by the cover member 130.

  However, since the cover member 130 does not shield the side surface of the dust collection box 120, the side surface of the dust collection box 120 is exposed to the outside. Accordingly, since at least a part of the side surface of the dust collection box 120 is made of a transparent material, the user can check the amount of dust collected in the storage space inside the dust collection box 120 with the naked eye. it can.

  When the suction port 124 is shielded by the cover member 130, the suction port 124 comes into contact with the outlet portion of the connector 134. Thereby, the connector 134 communicates with the suction port 124. At this time, the connector 134 may be aligned along the air inflow direction at the suction port 124.

  A first space 135 is formed inside the connector 134, and a second space 125 is formed inside the suction port 124. When the cover member 130 is closed, the first space 135 and the second space 125 are directly connected.

  On the other hand, when the cover member 130 is closed, the rear end of the connector 134 and the front end of the suction port 124 may be in close contact with each other to be in an airtight state, and all the air passing through the connector 134 is leaked to the outside. The dust can flow into the dust box 120 through the mouth 124.

  Hereinafter, this will be described in more detail. For convenience of explanation, the direction in which the suction hose 23 is connected (left side in FIG. 5) is forward, and the direction in contact with the dust collection box 120 is rear (in FIG. 5). (Right side).

  The opened rear end of the connector 134 may be extended to the inside of the cover member 130 and may be extended to a position corresponding to the opened front end of the suction port 124 when the cover member 130 is closed.

  A first sealing portion 136 may be formed at the rear end of the connector 134, and a second sealing portion 126 may be formed at the front end of the suction port 124. The first sealing part 136 and the second sealing part 126 may be formed in shapes corresponding to each other at positions facing each other, and may be configured to be in close contact with each other when the cover member 130 is closed.

  In more detail, the first sealing part 136 may be formed to have an inclination, and may have an inclination toward the front as it goes from the upper side to the lower side. The second sealing part 126 may be formed to be inclined in the same direction as the first sealing part 136. Similarly, the second sealing part 126 may be formed to have an inclination toward the front from the top to the bottom.

  Meanwhile, the direction of the inclined surfaces of the first sealing portion 136 and the second sealing portion 126 may be formed to correspond to the rotational direction in which the cover member 130 is opened and closed. The directions of the inclined surfaces of the first sealing portion 136 and the second sealing portion 126 may be formed to correspond to a tangent of the rotation radius of the cover member 130.

  That is, the rotation center of the cover member 130 is located at the rear end of the cover member 130, and the first sealing portion 136 and the first sealing portion 136 at a position away from the rotation center of the cover member 130 when the cover member 130 rotates. In order for the two sealing parts 126 to be in close contact with each other while sliding, the slopes of the first sealing part 136 and the second sealing part 126 are formed to have the same gradient as the tangent to the rotation radius of the cover member 130. Can be done.

  Due to the inclined structure of the first sealing portion 136 and the second sealing portion 126, the cover member 130 is not interfered by the connector 134 and the suction port 124 during the rotating operation of closing the cover member 130. Effectively airtight.

  The interior of the connector 134 and the interior of the suction port 124 may form a first space 135 and a second space 125, respectively. At this time, the rear end of the first space 135 and the second space 125 are formed. The front ends may have sizes corresponding to each other. The first sealing part 136 and the second sealing part 126 may have the same inclined surface. Therefore, the first space part 135 and the second space part 125 are completely in a state where the cover member 130 is closed. It can have the structure connected to.

  The first sealing part 136 and the second sealing part 126 may be formed together when the connector 134 and the suction port 124 are molded. That is, the first sealing portion 136 and the second sealing portion 126 may be formed of a plastic material, and may be integrally formed with the connector 134 and the suction port 124.

  If necessary, a sealing member for airtightness may be attached to the first sealing portion 136 and the second sealing portion 126. The sealing member may be formed around open ends of the first and second sealing portions 136 and 126 and may be attached to at least one of the first and second sealing portions 136 and 126. The sealing member may be formed of an elastic material such as rubber, silicon, or sponge. Accordingly, when the cover member 130 is closed, the space between the first sealing portion 136 and the second sealing portion 126 can be completely sealed by compressing the sealing member. In addition, the cover member 130 can be elastic when the cover member 130 is closed or opened, so that the impact when the cover member 130 is closed can be reduced, and the initial rotation can be made easier when the cover member 130 is opened. .

  Of course, the first sealing part 136 and the second sealing part 126 may be formed of another material having elasticity, if necessary. That is, the first sealing part 136 and the second sealing part 126 are separately formed of an elastic material such as rubber, silicon, sponge, etc., and then the rear end of the connector 134 and the front end of the suction port 124. It may be fixedly attached to.

  At this time, the first sealing portion 136 and the second sealing portion 126 may be mounted so as to be inclined, or may be formed so that surfaces contacting each other are inclined. The first sealing part 136 and the second sealing part 126 having elasticity may be formed with a predetermined thickness so that the cover member 130 can be compressed with the cover member 130 closed. The first sealing portion 136 and the second sealing portion 126 formed of an elastic material completely seal the first sealing portion 136 and the second sealing portion 126 so that the impact can be reduced when the cover member 130 is opened and closed. Opening can be facilitated.

  When the first sealing portion 136 and the second sealing portion 126 are formed of an elastic material, the first sealing portion 136 and the second sealing portion 126 are in close contact with each other while being pressed when the cover member 130 is closed. . Therefore, when the cover member 130 is closed, the first sealing portion 136 and the second sealing portion 126 are in close contact with each other in a compressed state, and the airtight performance between the connector 134 and the suction port 124 is further improved. Can do.

  Hereinafter, a case where the suction hose 23 is attached to the connector 134 will be described.

  FIG. 8 is a perspective view showing a state where the suction device is coupled to the cleaner body, and FIG. 9 is a longitudinal sectional view of FIG.

  Referring to FIGS. 8 and 9, the suction hose 23 is connected to the connector 134. A front end (left side in FIG. 9) to which the suction hose 23 is connected in the connector 134 can be defined as an inlet portion, and a rear end (right side in FIG. 9) from which air is discharged can be defined as an outlet portion. The outlet portions of the connector 134 face the suction port 124 and can contact each other.

  At this time, the outlet portion of the connector 134 communicates with the suction port 124, the first sealing portion 136 of the connector 134 and the second sealing portion 126 of the suction port 124 are in close contact with each other, and the connector 134 and the suction port The mouth 124 may be in a completely communicated state.

  Specifically, the air discharged from the suction hose 23 may flow into the dust collection box 120 through the first space 135 and the second space 125 sequentially. A flow path connecting the first space part 135 and the second space part 125 to the dust collection box 12 can be defined as a suction flow path F.

  As shown in the drawing, the suction flow path F flows from the connector 134 into the suction port 124, and is guided downward to move to the storage space.

  The suction flow path F can be divided into a first flow path defined in the first space part 135 and a second flow path defined in the second space part 125.

  When the connector 134 and the suction port 124 are connected, the first space part 135 and the second space part 125 are connected, thereby connecting the first flow path and the second flow path. One flow path is formed.

  In such a state, the flow path is connected in a straight line due to the close contact between the first sealing part 136 and the second sealing part 126, and the suction hose 23 is also attached to the connector 134 in a straight line. In particular, the air flowing in from the suction hose 23 can flow in a straight line toward the dust collection box 20 at the shortest distance.

  As described above, the airtightness between the suction hose 23 and the connector 134 can be maintained by the fitting parts 231, 232, and 233.

  The first fitting portion 231, the second fitting portion 232, and the third fitting portion 233 may be formed in order of increasing diameter. Accordingly, a step is formed between the first fitting portion 231 and the second fitting portion 232, and a step is also formed between the second fitting portion 232 and the third fitting portion 233.
