This application claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2020-0022975 filed on Feb. 25, 2020, whose entire disclosure is hereby incorporated by reference. This application is also related to U.S. application Ser. No. 16/861,954 filed Apr. 29, 2020, whose entire disclosure is also hereby incorporated by reference.
The present disclosure relates to a cleaner.
A cleaner is an appliance that sucks dusts or foreign matters to clean the room. A conventional cleaner generally includes a housing having an intake port and an exhaust hole, a fan for flowing air flowed into the intake port to the exhaust hole, a separator for separating the foreign matters from the air flowing by the fan, a filter located between the separator and the fan to filter the foreign matters from the air passed through the separator, and a handle disposed on the housing.
In a case of the above-mentioned conventional cleaner, most of the foreign matters contained in the air are separated from the air through the separator and stored in the housing, and the foreign matters contained in the air passed through the separator are separated from the air while passing through the filter. Accordingly, it may be seen that, the larger the volume of a storage space of the foreign matters defined in the housing, the greater the filtration capacity of the cleaner. However, when an amount of foreign matters remaining in filters is large, the filters will be a flow path resistance that reduces a flow rate of the air flowing to the fan. Thus, in some cases, a filtration capacity of the filters, rather than the volume of the housing, may become a factor that determines a filtration capacity of an entirety of the cleaner.
The embodiments will be described in detail with reference to the following drawings in which like reference numerals refer to like elements wherein:
Hereinafter, a preferred embodiment of a cleaner will be described in detail with reference to the drawings. A configuration or a method for controlling an apparatus to be described below is only for describing an embodiment of the present application, and is not intended to limit the scope of the present application. Further, like reference numerals throughout the specification indicate like components.
As shown in
The intake port 11 is disposed on a circumferential face of the housing 1 to flow outside air into the first space S1. The intake port 11 may include an intake hole 113 defined to penetrate the circumferential face of the housing 1, and an intake pipe 111 extending from the intake hole 113 in a direction to be farther away from a center of the housing 1 (a direction farther away from the handle, a Y-axis direction). Although not shown in the drawings, the cleaner of the present disclosure may further include an extended pipe detachably disposed on the intake pipe 111, and a nozzle disposed at a free end of the extended pipe to flow the foreign matters to the extended pipe.
The exhaust hole 153 is defined to penetrate a top face or a circumferential face of the housing 1 to exhaust air in the second space S2 to the outside of the housing 1. Further,
A housing through-hole 14 (see
A housing outlet 17 (see
A mounting portion (or mount) 2 is disposed inside the wall through-hole S3. The mounting portion 2 is for providing a mounting space 211 in which a first filter F1 to be described below is mounted. The mounting portion 2 may be disposed as a mounting body 21 detachably fixed to the housing wall 19 and positioned inside the wall through-hole S3.
The mounting body 21 may be disposed in a cylindrical or faceted cylindrical shape having a hollow therein.
As shown in
The bottom face 23 is divided into a first region 231 including a center of the bottom face, and a ring-shaped second region 233 surrounding the first region. The first communicating openings 25 is defined in the first region 231, and the second communicating openings 26 is defined in the second region 233.
The first communicating openings 25 may be defined as one hole penetrating the bottom face 23, or may be defined as a plurality of holes defined in the first region 231. Similarly, the second communicating openings 26 may be defined as one hole or a plurality of holes defined in the second region 233.
The mounting body 21 is detachably coupled to the housing wall 19 through a body fastening portion 27. As shown in
The separator 4 is fixed to the mounting body 21. Thus, when the user opens the housing outlet 17 with the lower cover 18 and pulls the separator 4 to the housing outlet 17, the mounting body 21 and the first filter F1 may be drawn out of the housing 1 together with the separator 4.
The fan 5 is disposed in the second space S2 to flow the air in the first space S1 to the exhaust hole 153 through the first communicating openings 25, the second communicating openings 26, and the top face through-hole 213. Further, the separator 4 is a flow path formed in the first space S1 to guide the air flowed into the intake port 11 to the two communicating openings 25 and 26. The foreign matters such as dust contained in the air are separated from the air by a centrifugal force while flowing to the fan 5 along the flow path provided by the separator 4, and a specific structure thereof is as follows.
The separator 4 includes a chamber forming portion (or chamber forming wall) 41 for dividing the first space S1 into a first separated chamber 41a and a second separated chamber 41b, and a cyclone forming portion (or cyclone forming cylinders) 42 for supplying the air in the second separated chamber 41b to the fan 5. The cyclone forming portion 42 is for providing the centrifugal force to the foreign matters contained in the air by rotating the air flowing to the fan 5.
The chamber forming portion 41 is formed in a hollow cylindrical shape. One end of the chamber forming portion 41 may be fixed to the bottom face 23 of the mounting body, and the other end of the chamber forming portion 41 may include a separated chamber body 411 in contact with the lower cover 18, and a separated chamber wall 417 for separating the second separated chamber 41b formed in the separated chamber body into a separated space 418 and a storage space 419.
The separated chamber body 411 includes a plurality of through-holes 413 communicating the first separated chamber 41a and the separated space 418 with each other. Therefore, the air flowed into the first separated chamber 41a through the intake port 11 may be supplied to the separated space 418 through the through-hole 413.
An outlet 415 is defined in a bottom face of the separated chamber body 411 in contact with the lower cover 18. Accordingly, the foreign matters stored in the storage space 419 may be discharged to the outside of the housing 1 through the outlet 415 when the lower cover 18 opens the housing outlet 17.
As shown in
The first communicating openings 25 and the second communicating openings 26 are defined as communicating holes penetrating the bottom face 23 of the mounting body. Each discharge pipe 424 may be disposed as a pipe fixed to each of the communicating holes. Each flow path body 421 may be fixed to the bottom face 23 of the mounting body and having each pipe fixed to each communicating hole.
In one example, each foreign matter outlet 422 is defined at a free end of each flow path body 421 (a bottom face of the flow path body) positioned in the storage space 419. Thus, each flow path body 421 may be in communication with the storage space 419 through each foreign matter outlet 422. Each flow path body 421 may be disposed to decrease in diameter toward the free end thereof. This is to strongly maintain a strength of the air flow formed therein.
Each inlet 423 is located at a point higher than each air flow forming portion 425. Therefore, when the fan 5 is operated, the air flowing into the flow path body 421 through the inlet 423 flows to the discharge pipe 424 via the air flow forming portion 425. In this process, the air will flow while rotating inside the flow path body 421 (e.g., a cyclone flow). When the cyclone flow occurs in the flow path body 421, the foreign matters contained in the air will flow to an edge of the flow path (the circumferential face of the flow path body) by the centrifugal force, and then be discharged to the storage space 419 by gravity.
Each cyclone forming portion 42 having the above-described structure may include each first cyclone forming portion connected to each communicating hole of the first communicating openings 25, and each second cyclone forming portion connected to each communicating hole of the second communicating openings 26. The number of first cyclone forming portions may be equal to the number of communicating holes constituting the first communicating openings 25, and the number of second cyclone forming portions may be equal to the number of communicating holes constituting the second communicating openings 26.
As shown in
The casing 51 may be disposed in a hollow cylinder shape. Further, a casing intake hole 511 and a casing exhaust hole 513 are defined in the casing 51. It is preferable that the casing intake hole 511 is defined in one face of the casing 51 inserted into the mounting space 211, and the casing exhaust hole 513 directed toward the exhaust hole 153 is defined to penetrate one face of the casing 51.
The motor 54 may be fixed to a support 515 fixed inside the casing 51. In this case, the casing exhaust hole 513 may be defined as a support through-hole passing through the support 515. The impeller 57 is disposed to be positioned between the casing intake hole 511 and the casing exhaust hole 513, and a rotation shaft 541 of the motor penetrates through the support 515 and is connected to the impeller 57.
The motor 54 may be disposed to receive power through a power source disposed in the room, or may be disposed to receive the power through a battery 65 detachable from the housing 1. When the handle 6 is disposed to include a handle body 61 protruding in a direction farther away from the intake port on a rear face (a face opposite to the face on which the intake port is positioned) of the housing 1, the handle body 61 may include a battery housing 63 in which the battery 65 is detachably accommodated.
In one example, in order for filtration of the foreign matters, which is not removed through the separator 4, the present disclosure may further include filters F1 and F2. The filters further includes at least one of a first filter F1 and a second filter F2.
The first filter F1 may be located between the casing intake hole 511 and the mounting body bottom face 23 to filter the air, and the second filter F2 may be located between the casing exhaust hole 513 and the exhaust hole 153 to filter the air. The first filter F1 and the second filter F2 may be disposed to filter foreign matters of the same size, or may be disposed to filter foreign matters of different sizes. When the first filter F1 and the second filter F2 are disposed to filter the foreign matters of different sizes, it is preferable that the second filter F2 is disposed to filter foreign matters of a size smaller than a size of the foreign matters filtered by the first filter F1. This is to minimize an amount of fine dusts discharged to an indoor space.
As shown in
When the air rotates inside the first separated chamber 41a, the foreign matters in the air flow to the circumferential face of the first separated chamber 41a by a centrifugal force, and then flows to the lower cover 18 disposed on the bottom face of the housing by gravity. Further, the air will flow through the through-hole 413 to the second separated chamber 41b.
The air flowed to the second separated chamber 41b will flow to the flow path body 421 through the inlet 423, and the air flowed into the flow path body 421 will flow cyclonically while passing through the air flow forming portion 425. When the cyclone flow occurs in the flow path body 421, the foreign matters contained in the air will flow to the circumferential face of the flow path body 421 by a centrifugal force and then be discharged to the storage space 419 by gravity. Further, the air will be discharged out of the housing 1 through the discharge tube 424, the first communicating openings 25, the second communicating openings 26, the top face through-hole 213, the casing intake hole 511, the casing exhaust hole 513, and the exhaust hole 153. The foreign matters stored in the storage space 419 and the first separated chamber 41a are discharged to the outside of the housing 1 when the lower cover 18 opens the housing outlet 17.
Further, in the cleaner 100 having the above-described structure, a volume of the first filter F1 is limited by a volume of the mounting space 211, so that a filtration capacity of the first filter F1 is limited by the volume of the mounting space 211. In addition, in the cleaner 100 having the above-described structure, among filter faces provided by the first filter F1, only a filter face (a filter face in which the first communicating openings and the second communicating openings are defined) facing the bottom face 23 of the mounting body functions to filter the foreign matters. That is, the filter faces of the first filter F1 which do not face the bottom face 23 of the mounting body do not serve to separate the foreign matters from the air. This may cause a problem that the first filter F1 does not perform the function of filtering the air when a lot of foreign matters are accumulated on the filter face facing the bottom face 23 of the mounting body even when other filter faces of the first filter F1 are in a state of being able to filter the foreign matters.
As shown in
As shown in portion A of
The first chamber forming portion 851 is disposed to form a first filtering chamber C1 in communication only with the first communicating hole 261 in the mounting space 211, the second chamber forming portion 853 is disposed to form a second filtering chamber C2 in communication only with the second communicating hole 263 in the mounting space 211, and the third chamber forming portion 855 is disposed to form a third filtering chamber C3 in communication only with the third communicating hole 265 in the mounting space 211. It is preferable that the chamber forming portions 851, 853, and 855 are arranged such that the first filtering chamber C1, the second filtering chamber C2, and the third filtering chamber C3 are independent of each other.
The air flowed into the first communicating openings 25 passes through the first filter face 83 and then flows to the fan 5. Further, the air flowed into the first communicating hole 261 of the second communicating openings passes through the first filtering chamber C1 and then flows to the fan. Further, the air flowed into the second communicating hole 263 passes through the second filtering chamber C2 and then flows to the fan. Further, the air flowed into the third communicating hole 265 passes through the third filtering chamber C3 and then flows to the fan. Therefore, the first filter F1 having the above-described structure has an effect that the first filter face 83 and the second filter face 85 all filter the foreign matters.
When the second filter face 85 is disposed to be in close contact with an inner circumferential face of the mounting body 21 (when no chamber forming portions are arranged on the second filter face), the air flowed into the first communicating openings 25 and the second communicating openings 26 may pass through only the first filter face 83 and then flow to the fan 5. In this case, the second filter face 85 may not be able to perform a function of filtering the air, but the above-described first filter F1 may prevent such a problem. In addition, the first filter F1 described above may maximize a surface area of the second filter face 85, so that a filtration capacity of the filter located in the mounting space 211 with a limited volume may be maximized.
Portion B of
Portion C of
The fifth chamber forming portion 859 forms a fifth filtering chamber C5 in communication only with the fifth communicating hole 269 inside the mounting space by bending the surface of the second filter 85 toward the center of the filter body 81. The fifth filtering chamber C5 is preferably disposed as an independent space separate from the first filtering chamber C1, the second filtering chamber C2, the third filtering chamber C3, and the fourth filtering chamber C4.

It will be understood that when an element or layer is referred to as being “on” another element or layer, the element or layer can be directly on another element or layer or intervening elements or layers. In contrast, when an element is referred to as being “directly on” another element or layer, there are no intervening elements or layers present. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.
It will be understood that, although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section could be termed a second element, component, region, layer or section without departing from the teachings of the present invention.
Spatially relative terms, such as “lower”, “upper” and the like, may be used herein for ease of description to describe the relationship of one element or feature to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation, in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “lower” relative to other elements or features would then be oriented “upper” relative to the other elements or features. Thus, the exemplary term “lower” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
Embodiments of the disclosure are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the disclosure should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing.
Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Any reference in this specification to “one embodiment,” “an embodiment,” “example embodiment,” etc., means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the invention. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with any embodiment, it is submitted that it is within the purview of one skilled in the art to effect such feature, structure, or characteristic in connection with other ones of the embodiments.
Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
