CROSS-REFERENCE TO RELATED APPLICATIONS

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.

BACKGROUND

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.

DETAILED DESCRIPTION

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.

FIG. 1illustrates an example of a cleaner100. The cleaner100includes a housing1formed in a form of a cylinder with a hollow therein, an intake port11formed on the housing1and an exhaust hole153defined in the housing1, a fan5disposed inside the housing1to flow air from the intake port11to the exhaust hole153, a separator4for guiding the air flowed into the intake port11to the fan5, and separating foreign matters from the air using a centrifugal force, and a handle6disposed on the housing1such that a user may grab the handle6with a hand. The handle6may be positioned at a point that is symmetrical with (180 degrees apart from) a point where the intake port11is located in a space provided by a circumferential face of the housing1.

As shown inFIG. 2, a housing wall19for dividing an internal space of the housing into a lower space (a first space, S1) and an upper space (a second space, S2) of the housing is disposed inside the housing1. Further, the housing wall19includes a wall through-hole S3for communicating the first space S1and the second space S2with each other defined therein.

The intake port11is disposed on a circumferential face of the housing1to flow outside air into the first space S1. The intake port11may include an intake hole113defined to penetrate the circumferential face of the housing1, and an intake pipe111extending from the intake hole113in a direction to be farther away from a center of the housing1(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 pipe111, and a nozzle disposed at a free end of the extended pipe to flow the foreign matters to the extended pipe.

The exhaust hole153is defined to penetrate a top face or a circumferential face of the housing1to exhaust air in the second space S2to the outside of the housing1. Further,FIG. 2illustrates an example in which the exhaust hole153is defined in the top face of the housing1.

A housing through-hole14(seeFIG. 1) may be defined in the top face of the housing1, and the housing through-hole14may be defined to be opened and closed by an upper cover151. A second filter F2for filtering the air discharged from the fan5may be disposed inside the housing, and the user may separate the second filter F2from the housing1by separating the upper cover151from the housing through-hole14. The upper cover151may be disposed in a shape corresponding to a shape of the housing through-hole14, and the exhaust hole153may include a plurality of holes penetrating the upper cover151.

A housing outlet17(seeFIG. 1) for discharging the foreign matters stored in the housing1to the outside is further defined in a bottom face (one face of the housing opposite to the face in which the exhaust hole153is defined) of the housing1. The housing outlet17is opened and closed by a lower cover18. The lower cover18may be rotatably fixed to the housing1.

A mounting portion (or mount)2is disposed inside the wall through-hole S3. The mounting portion2is for providing a mounting space211in which a first filter F1to be described below is mounted. The mounting portion2may be disposed as a mounting body21detachably fixed to the housing wall19and positioned inside the wall through-hole S3.

The mounting body21may be disposed in a cylindrical or faceted cylindrical shape having a hollow therein.FIG. 2illustrates an example in which the mounting body21is formed in a cylindrical shape in which the mounting space211is defined.

As shown inFIG. 3, a top face through-hole213for communicating the mounting space211and the second space S2with each other is defined in a top face of the mounting body21, and first communicating openings25and second communicating openings26for communicating the mounting space211with the first space S1are defined in a bottom face23of the mounting body.

The bottom face23is divided into a first region231including a center of the bottom face, and a ring-shaped second region233surrounding the first region. The first communicating openings25is defined in the first region231, and the second communicating openings26is defined in the second region233.

The first communicating openings25may be defined as one hole penetrating the bottom face23, or may be defined as a plurality of holes defined in the first region231. Similarly, the second communicating openings26may be defined as one hole or a plurality of holes defined in the second region233.

The mounting body21is detachably coupled to the housing wall19through a body fastening portion27. As shown inFIG. 2, the body fastening portion27may include a protrusion271disposed on an outer circumferential face of the mounting body21, and a protrusion fastening groove237defined in the housing wall19and positioned in the wall through-hole S3, wherein the protrusion fastening groove237provides a space in which the protrusion271is accommodated.

The separator4is fixed to the mounting body21. Thus, when the user opens the housing outlet17with the lower cover18and pulls the separator4to the housing outlet17, the mounting body21and the first filter F1may be drawn out of the housing1together with the separator4.

The fan5is disposed in the second space S2to flow the air in the first space S1to the exhaust hole153through the first communicating openings25, the second communicating openings26, and the top face through-hole213. Further, the separator4is a flow path formed in the first space S1to guide the air flowed into the intake port11to the two communicating openings25and26. The foreign matters such as dust contained in the air are separated from the air by a centrifugal force while flowing to the fan5along the flow path provided by the separator4, and a specific structure thereof is as follows.

The separator4includes a chamber forming portion (or chamber forming wall)41for dividing the first space S1into a first separated chamber41aand a second separated chamber41b, and a cyclone forming portion (or cyclone forming cylinders)42for supplying the air in the second separated chamber41bto the fan5. The cyclone forming portion42is for providing the centrifugal force to the foreign matters contained in the air by rotating the air flowing to the fan5.

The chamber forming portion41is formed in a hollow cylindrical shape. One end of the chamber forming portion41may be fixed to the bottom face23of the mounting body, and the other end of the chamber forming portion41may include a separated chamber body411in contact with the lower cover18, and a separated chamber wall417for separating the second separated chamber41bformed in the separated chamber body into a separated space418and a storage space419.

The separated chamber body411includes a plurality of through-holes413communicating the first separated chamber41aand the separated space418with each other. Therefore, the air flowed into the first separated chamber41athrough the intake port11may be supplied to the separated space418through the through-hole413.

An outlet415is defined in a bottom face of the separated chamber body411in contact with the lower cover18. Accordingly, the foreign matters stored in the storage space419may be discharged to the outside of the housing1through the outlet415when the lower cover18opens the housing outlet17.

As shown inFIG. 3, each cyclone forming portion42may have one end fixed to the bottom face23of the mounting body, and the other end including a flow path body421penetrating through the separated chamber wall417and in communication with the storage space419, each discharge pipe424having one end connected to the mounting space211and the other end located inside the flow path body421, each inlet423defined to penetrate a circumferential face of the flow path body421, and each air flow forming portion425forming a spiral flow path between an outer circumferential face of the discharge pipe424and an inner circumferential face of the flow path body.

The first communicating openings25and the second communicating openings26are defined as communicating holes penetrating the bottom face23of the mounting body. Each discharge pipe424may be disposed as a pipe fixed to each of the communicating holes. Each flow path body421may be fixed to the bottom face23of the mounting body and having each pipe fixed to each communicating hole.

In one example, each foreign matter outlet422is defined at a free end of each flow path body421(a bottom face of the flow path body) positioned in the storage space419. Thus, each flow path body421may be in communication with the storage space419through each foreign matter outlet422. Each flow path body421may 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 inlet423is located at a point higher than each air flow forming portion425. Therefore, when the fan5is operated, the air flowing into the flow path body421through the inlet423flows to the discharge pipe424via the air flow forming portion425. In this process, the air will flow while rotating inside the flow path body421(e.g., a cyclone flow). When the cyclone flow occurs in the flow path body421, 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 space419by gravity.

Each cyclone forming portion42having the above-described structure may include each first cyclone forming portion connected to each communicating hole of the first communicating openings25, and each second cyclone forming portion connected to each communicating hole of the second communicating openings26. The number of first cyclone forming portions may be equal to the number of communicating holes constituting the first communicating openings25, and the number of second cyclone forming portions may be equal to the number of communicating holes constituting the second communicating openings26.

As shown inFIG. 2, the fan5is disposed in the second space S2of the housing to flow the air flowed into the first communicating openings25and the second communicating openings26to the exhaust hole153. The fan5may include a casing51disposed in the second space S2, an impeller57rotatably disposed inside the casing, and a motor54fixed to the casing to rotate the impeller57.

The casing51may be disposed in a hollow cylinder shape. Further, a casing intake hole511and a casing exhaust hole513are defined in the casing51. It is preferable that the casing intake hole511is defined in one face of the casing51inserted into the mounting space211, and the casing exhaust hole513directed toward the exhaust hole153is defined to penetrate one face of the casing51.

The motor54may be fixed to a support515fixed inside the casing51. In this case, the casing exhaust hole513may be defined as a support through-hole passing through the support515. The impeller57is disposed to be positioned between the casing intake hole511and the casing exhaust hole513, and a rotation shaft541of the motor penetrates through the support515and is connected to the impeller57.

The motor54may be disposed to receive power through a power source disposed in the room, or may be disposed to receive the power through a battery65detachable from the housing1. When the handle6is disposed to include a handle body61protruding 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 housing1, the handle body61may include a battery housing63in which the battery65is detachably accommodated.

In one example, in order for filtration of the foreign matters, which is not removed through the separator4, the present disclosure may further include filters F1and F2. The filters further includes at least one of a first filter F1and a second filter F2.FIG. 2illustrates an example in which the filters includes both the first filter F1and the second filter F2.

The first filter F1may be located between the casing intake hole511and the mounting body bottom face23to filter the air, and the second filter F2may be located between the casing exhaust hole513and the exhaust hole153to filter the air. The first filter F1and the second filter F2may 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 F1and the second filter F2are disposed to filter the foreign matters of different sizes, it is preferable that the second filter F2is 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 inFIG. 4, when electric power is supplied to the motor54and the impeller57rotates, the air is flowed into the first separated chamber41athrough the intake pipe111and the intake hole113. The intake pipe111includes a housing guide115that allows the air discharged from the intake hole113to inflow in a tangential direction of a circumferential face of the first separated chamber41a. Therefore, the air flowed into the first separated chamber41awill rotate along the circumferential face of the first separated chamber41a.

When the air rotates inside the first separated chamber41a, the foreign matters in the air flow to the circumferential face of the first separated chamber41aby a centrifugal force, and then flows to the lower cover18disposed on the bottom face of the housing by gravity. Further, the air will flow through the through-hole413to the second separated chamber41b.

The air flowed to the second separated chamber41bwill flow to the flow path body421through the inlet423, and the air flowed into the flow path body421will flow cyclonically while passing through the air flow forming portion425. When the cyclone flow occurs in the flow path body421, the foreign matters contained in the air will flow to the circumferential face of the flow path body421by a centrifugal force and then be discharged to the storage space419by gravity. Further, the air will be discharged out of the housing1through the discharge tube424, the first communicating openings25, the second communicating openings26, the top face through-hole213, the casing intake hole511, the casing exhaust hole513, and the exhaust hole153. The foreign matters stored in the storage space419and the first separated chamber41aare discharged to the outside of the housing1when the lower cover18opens the housing outlet17.

Further, in the cleaner100having the above-described structure, a volume of the first filter F1is limited by a volume of the mounting space211, so that a filtration capacity of the first filter F1is limited by the volume of the mounting space211. In addition, in the cleaner100having 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 face23of the mounting body functions to filter the foreign matters. That is, the filter faces of the first filter F1which do not face the bottom face23of the mounting body do not serve to separate the foreign matters from the air. This may cause a problem that the first filter F1does not perform the function of filtering the air when a lot of foreign matters are accumulated on the filter face facing the bottom face23of the mounting body even when other filter faces of the first filter F1are in a state of being able to filter the foreign matters.

FIG. 5illustrates an example of the first filter F1in which all filter faces thereof are able to filter the air, thereby maximizing the filtration capacity. The first filter F1may include a filter body81having a cup shape (a cylindrical shape with open top face) located in the mounting space211, a first filter face83disposed on a face facing the bottom face of a space provided by the filter body81to filter the air flowed into the first communicating openings25, and a second filter face85disposed on the filter body81to filter the air flowed into the second communicating openings26.

As shown inFIG. 6, the second filter face85is disposed to divide the mounting space211into a space in which the first communicating openings25is defined (a space in which the first region is located) and a space in which the second communicating openings26is defined (a space in which the second region is located). That is, the second filter face85includes a plurality of chamber forming portions (or chamber forming walls)851,853,855,857, and859arranged on a side face of the filter body81, and respectively forming a plurality of filtering chambers of the number equal to the number of communicating holes constituting the first communicating openings25and the second communicating openings26in the mounting space211.

As shown in portion A ofFIG. 7, when the second communicating openings26is defined as a first communicating hole261, a second communicating hole263, and a third communicating hole265, the chamber forming portions may be arranged as a first chamber forming portion851, a second chamber forming portion853, and a third chamber forming portion855. The first chamber forming portion851, the second chamber forming portion853, and the third chamber forming portion855may be formed in shapes bent from the second filter face85(the side face of the filter body) toward a center of the filter body81.

The first chamber forming portion851is disposed to form a first filtering chamber C1in communication only with the first communicating hole261in the mounting space211, the second chamber forming portion853is disposed to form a second filtering chamber C2in communication only with the second communicating hole263in the mounting space211, and the third chamber forming portion855is disposed to form a third filtering chamber C3in communication only with the third communicating hole265in the mounting space211. It is preferable that the chamber forming portions851,853, and855are arranged such that the first filtering chamber C1, the second filtering chamber C2, and the third filtering chamber C3are independent of each other.

The air flowed into the first communicating openings25passes through the first filter face83and then flows to the fan5. Further, the air flowed into the first communicating hole261of the second communicating openings passes through the first filtering chamber C1and then flows to the fan. Further, the air flowed into the second communicating hole263passes through the second filtering chamber C2and then flows to the fan. Further, the air flowed into the third communicating hole265passes through the third filtering chamber C3and then flows to the fan. Therefore, the first filter F1having the above-described structure has an effect that the first filter face83and the second filter face85all filter the foreign matters.

When the second filter face85is disposed to be in close contact with an inner circumferential face of the mounting body21(when no chamber forming portions are arranged on the second filter face), the air flowed into the first communicating openings25and the second communicating openings26may pass through only the first filter face83and then flow to the fan5. In this case, the second filter face85may not be able to perform a function of filtering the air, but the above-described first filter F1may prevent such a problem. In addition, the first filter F1described above may maximize a surface area of the second filter face85, so that a filtration capacity of the filter located in the mounting space211with a limited volume may be maximized.

Portion B ofFIG. 7illustrates a case in which the second communicating openings26is defined as the first communicating hole261, the second communicating hole263, the third communicating hole265, and a fourth communicating hole267. In this case, the chamber forming portions should be arranged as the first chamber forming portion851, the second chamber forming portion853, the third chamber forming portion855, and a fourth chamber forming portion857. The fourth chamber forming portion857forms a fourth filtering chamber C4in communication only with the fourth communicating hole267inside the mounting space by bending a surface of the second filter85toward the center of the filter body81. The fourth filtering chamber C4is preferably disposed as an independent space separate from the first filtering chamber C1, the second filtering chamber C2, and the third filtering chamber C3.

Portion C ofFIG. 7illustrates a case in which the second communicating openings26is defined as the first communicating hole261, the second communicating hole263, the third communicating hole265, the fourth communicating hole267, and a fifth communicating hole269. In this case, the chamber forming portions should be arranged as the first chamber forming portion851, the second chamber forming portion853, the third chamber forming portion855, the fourth chamber forming portion857, and a fifth chamber forming portion859.

The fifth chamber forming portion859forms a fifth filtering chamber C5in communication only with the fifth communicating hole269inside the mounting space by bending the surface of the second filter85toward the center of the filter body81. The fifth filtering chamber C5is 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.

The fourth communicating hole267is defined as a fourth chamber first hole267aand a fourth chamber second hole267b. Further, the fifth communicating hole269is defined as a fifth chamber first hole269aand a fifth chamber second hole269b. The mounting body21may further include guides281,283,285,287, and289, each of which separates two chamber holes defined in one filtering chamber from each other.

Portion A ofFIG. 8illustrates a case in which the guide includes a first guide281that divides the first filtering chamber C1into two spaces to separate the first chamber first hole261aand the first chamber second hole261bfrom each other, a second guide283that divides the second filtering chamber C2into two spaces to separate the second chamber first hole263aand the second chamber second hole263bfrom each other, and a third guide285that divides the third filtering chamber C3into two spaces to separate the third chamber first hole265aand the third chamber second hole265bfrom each other.

Portion B ofFIG. 8illustrates an embodiment in which the guide further includes a fourth guide287that divides the fourth filtering chamber C4into two spaces to separate the fourth chamber first hole267aand the fourth chamber second hole267bfrom each other, and portion C ofFIG. 8illustrates an embodiment in which the guide further includes a fifth guide289that divides the fifth filtering chamber C5into two spaces to separate the fifth chamber first hole269aand the fifth chamber second hole269bfrom each other.

The embodiments ofFIGS. 7 and 8illustrate examples in which the first communicating openings25is defined as one communicating hole. However, the first communicating openings25may also be defined as a plurality of communicating holes.

The first filter F1illustrated inFIGS. 7 and 8have shapes in which each of the chamber forming portions851,853,855,857, and859protrude sharply toward the center of the filter body81. However, each chamber forming portion is not necessarily formed in a sharply protruding shape.

FIG. 9illustrates another embodiment of the first filter F1. Portions A to C ofFIG. 9illustrate an example of the first filter F1in which each of the chamber forming portions851,853,855,857, and859is disposed as a face concavely curved toward the center of the filter body81.

In the cleaner having the above-described structure, when the user separates the separator4from the housing1, the first filter F1may be separated from the housing1together with the separator4. That is, as shown inFIG. 11, when the user opens the housing outlet17with the lower cover18and then pulls the separator4toward the housing outlet17, the mounting body21and the first filter F1seated in the mounting body21may be drawn out of the housing1together with the separator4. This is because the separator4may be fixed to the mounting body21, and the mounting body21is detachably coupled to the protrusion fastening groove273defined in the housing wall19through the protrusion271. When the mounting body21and the first filter F1are withdrawn from the housing1, the user may detach the first filter F1from the mounting body21. Therefore, the cleaner having the above-described structure has an effect of facilitating separation and cleaning of the first filter F1.
