Description

vacuum cleaner

[0001] The present disclosure relates to a cleaning device.

[0002] In general, a vacuum cleaner is a device that includes a fan motor that generates suction force, sucks in foreign substances such as dust along with the air through the suction force generated by the fan motor, separates the foreign substances contained in the sucked air from the air, and then collects the dust to perform cleaning.

[0003] The vacuum cleaner includes a dust bin that collects foreign substances, and the user must periodically separate the foreign substances collected in the dust bin from the vacuum cleaner and discharge them from the dust bin.

[0004] To reduce the inconvenience of users having to manually remove foreign substances from the dustbin, a docking station designed to automatically discharge foreign substances from the dustbin may be used. The docking station may include a dust bag designed to store foreign substances discharged from the dustbin of the vacuum cleaner.

[0005] Depending on the usage environment of the vacuum cleaner and docking station, mold and pests may grow inside the vacuum cleaner's dust bin and the docking station's dust bag.

[0006] One aspect of the present disclosure provides a vacuum cleaner capable of preventing the growth of mold and / or pests inside a dustbin.

[0007] One aspect of the present disclosure provides a vacuum cleaner that removes moisture inside a dustbin by supplying high temperature air into the dustbin, thereby preventing the growth of mold and / or pests inside the dustbin.

[0042] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the attached drawings.

[0043] Figure 1 illustrates a cleaner of a cleaning device according to one embodiment.

[0044] Referring to FIG. 1, a cleaner (2) may include a cleaner body (10) configured to generate suction force, a suction nozzle (11) connected to the cleaner body (10) to suck up foreign substances on a surface to be cleaned through the suction force generated by the cleaner body (10), and an extension pipe (30) connecting the cleaner body (10) and the suction nozzle (11). The suction nozzle may be referred to by other terms such as a suction head, a suction portion, a suction unit, a suction module, etc.

[0045] The vacuum cleaner (2) may include a dust bin (20) that is coupled to the vacuum cleaner body (10). The dust bin (20) may be detachably coupled to the vacuum cleaner body (10). However, the present invention is not limited thereto. The dust bin (20) may be provided so that at least one side is openable and may not be detachable from the vacuum cleaner body (10).

[0046] A dust bin (20) may be provided to collect foreign substances moved into the vacuum cleaner (2). The dust bin (20) may be configured to filter and store foreign substances from the air and foreign substances flowing into the vacuum cleaner body (10) through the suction nozzle (11). The foreign substances may refer to dust or dirt, etc.

[0047] The vacuum cleaner body (10) may include a vacuum cleaner motor (62, FIG. 21) that generates suction force necessary to suck up foreign substances on a surface to be cleaned. The vacuum cleaner motor (62) may be configured to convert electrical power into mechanical rotational power. The vacuum cleaner body (10) may include a fan that is connected to the vacuum cleaner motor (62) and configured to rotate. As the fan rotates, a flow of air that sucks up foreign substances on the surface to be cleaned may be generated. The vacuum cleaner motor (62) may be referred to by other terms such as a suction motor, a driving motor, and a suction power generating device.

[0048] The dust bin (20) can collect foreign substances using a cyclone method that separates foreign substances using centrifugal force, or a dust bag method that separates foreign substances by passing air through a filter bag. Air from which foreign substances have been removed through the dust bin (20) can be discharged to the outside of the vacuum cleaner body (10).

[0049] The vacuum cleaner body (10) may include a filter housing. The filter housing is configured in a roughly donut shape and can accommodate a filter (14) therein. There is no limitation on the type of filter, but as an example, a HEPA (High Efficiency Particulate Air, Hepa) filter may be placed inside the filter housing. The filter may filter ultrafine dust and the like that are not filtered out in the dust bin (20).

[0050] The vacuum cleaner body (10) may include a handle (15) so that a user can hold and operate the vacuum cleaner (2). The user can hold the handle (15) and move the vacuum cleaner (2) to clean.

[0051] The vacuum cleaner body (10) may further include a vacuum cleaner control unit. The user can turn the vacuum cleaner (2) on / off by operating a power button (12) provided on the vacuum cleaner control unit. The user can adjust the suction strength of the vacuum cleaner (2) by operating a control button (13) provided on the vacuum cleaner control unit.

[0052] The vacuum cleaner (2) may include an extension pipe (30) that is detachably connected to the vacuum cleaner body (10). The extension pipe (30) may be formed of a pipe or a flexible hose having a predetermined rigidity. A suction nozzle (11) may be detachably connected to the extension pipe (30). One end of the extension pipe (30) may be detachably connected to the vacuum cleaner body (10), and the suction nozzle (11), a heat generator (100) to be described later, or a mop cleaning unit may be detachably connected to the other end of the extension pipe (30). The extension pipe (30) may be provided so as to be extendable or retractable within a predetermined range along the direction in which the extension pipe (30) extends.

[0053] The suction nozzle (11) may be provided to suck external foreign substances into the interior of the cleaner (2). An extension pipe (30) may be provided to connect the cleaner body (10) and the suction nozzle (11) to form a path for air and foreign substances to move. The sucked foreign substances may pass through the cleaner body (10) and be collected by moving to the dust bin (20). The extension pipe (30) may be provided to connect the suction nozzle (11) and the dust bin (20).

[0054] The extension pipe (30) may be provided with a first extension pipe connector (33) and a second extension pipe connector. The first extension pipe connector (33) may be provided at one end (31) of the extension pipe (30) connected to the cleaner body (10). The second extension pipe connector may be provided at the other end (32) of the extension pipe (30) connected to the suction nozzle (11), the heat generator (100), or the mop cleaning unit. The first extension pipe connector (33) may be provided to contact a body connector (61, FIG. 21) provided on the cleaner body (10). When the extension pipe (30) is coupled to the cleaner body (10), the first extension pipe connector (33) may be provided to contact the body connector (61). When the first extension pipe connector (33) and the body connector (61) are in contact, the first extension pipe connector (33) and the body connector (61) may be electrically connected. When the first extension tube connector (33) is electrically connected to the main body connector (61), the second extension tube connector connected to the first extension tube connector (33) can be electrically connected to the main body connector (61). The first extension tube connector (33) and the second extension tube connector can be connected by a wire extending along the direction in which the extension tube (30) extends.

[0055] Since the extension pipe (30) includes the first extension pipe connector (33) and the second extension pipe connector, a suction nozzle (11) or a heat generator (100) or a mop cleaning unit, etc., which are coupled to the other end (32) of the extension pipe (30), can be electrically connected to the cleaner body (10). In other words, the suction nozzle (11) or the heat generator (100) or the mop cleaning unit, which are coupled to the other end (32) of the extension pipe (30), can operate by receiving power from the battery (16) of the cleaner (2). The suction nozzle (11) or the heat generator (100) or the mop cleaning unit can each include a connector to receive power from the battery (16). Each of the connectors can be electrically connected by making contact with the second extension pipe connector.

[0056] The vacuum cleaner (2) may further include a battery (16). The battery (16) may be detachably mounted on the vacuum cleaner body (10). The battery (16) may be provided so that it can be easily detached and mounted from the vacuum cleaner body (10) without a separate device. Alternatively, the battery (16) may be provided so that it can be detached from the vacuum cleaner body (10) after disassembling at least one fastening member fastened to the vacuum cleaner body (10).

[0057] The battery (16) can be electrically connected to a charging terminal provided in the vacuum cleaner holder or the docking station (3) described later. The battery (16) can be charged by receiving power from the charging terminal provided in the vacuum cleaner holder or the docking station (3). The battery (16) can be coupled to the vacuum cleaner body (10) to supply power to the vacuum cleaner motor (62).

[0058] Figure 2 illustrates the vacuum cleaner illustrated in Figure 1 with the suction nozzle connected to the extension tube separated and the heat generator attached. Figure 3 illustrates the vacuum cleaner illustrated in Figure 2 in an exploded view. Figure 4 illustrates the vacuum cleaner illustrated in Figure 2 with the extension tube separated from the vacuum cleaner body and the heat generator directly attached to the vacuum cleaner body.

[0059] Referring to FIGS. 2 to 4, the cleaner (2) of the cleaning device (1) according to one embodiment may include a heat generator (100) that is directly or indirectly detachably coupled to the cleaner body (10). That the heat generator (100) is indirectly coupled to the cleaner body (10) may mean that the heat generator (100) is coupled to the cleaner body (10) via an extension pipe (30). In other words, as illustrated in FIG. 2, when the heat generator (100) is coupled to the extension pipe (30) and the extension pipe (30) is coupled to the cleaner body (10), it can be said that the heat generator (100) is indirectly coupled to the cleaner body (10). The fact that the heat generator (100) is directly coupled to the cleaner body (10) may mean that the heat generator (100) is directly coupled to the cleaner body (10) without an extension tube (30), as shown in FIG. 4.

[0060] The heat generator (100) can be detachably coupled to the cleaner body (10). The heat generator (100) can be detachably coupled to an extension tube (30). One end (31) of the extension tube (30) can be detachably coupled to the cleaner body (10), and the heat generator (100) can be detachably coupled to the other end (32) of the extension tube (30).

[0061] The heat generator (100) may be configured to heat air. When the heat generator (100) is coupled to the vacuum cleaner body (10), high-temperature air heated by the heat generator (100) may be introduced into the dust bin (20). When the heat generator (100) is coupled to the vacuum cleaner body (10), the heat generator (100) may be powered by the battery (16) of the vacuum cleaner (2). The heat generator (100) may be operated by receiving power from the battery (16) of the vacuum cleaner (2).

[0062] The heat generator (100) can heat air to 50°C or higher. The heat generator (100) can heat air to 50°C or higher to eliminate pests. For example, the heat generator (100) can heat air introduced into the heat generator (100) to 50°C to 80°C.

[0063] When the heat generator (100) and the vacuum cleaner motor (62) operate, high-temperature air heated by the heat generator (100) by the suction force generated by the vacuum cleaner motor (62) can be drawn into the dust bin (20). The high-temperature air may refer to air heated to 50°C or higher by the heat generator (100).

[0064] The vacuum cleaner's dustbin can store mold and pests, which are contained in foreign substances sucked from the surface being cleaned. If mold and pests are stored inside the dustbin for an extended period, they can multiply. In particular, high temperatures and humidity inside the dustbin increase the likelihood of mold and pests multiplying. For example, during hot and humid summers, and when moisture-containing foreign substances from the surface being cleaned enter the dustbin, mold and pests can multiply within the dustbin.

[0065] According to the present disclosure, the vacuum cleaner (2) can remove mold and pests inside the dustbin (20) by including a heat generator (100), and can suppress the growth of mold and pests inside the dustbin (20). When air of 50°C or higher heated by the heat generator (100) flows into the dustbin (20), mold and pests can be removed by the high-temperature air. When air of 50°C or higher heated by the heat generator (100) flows into the dustbin (20), moisture inside the dustbin (20) can be removed, and as a result, the inside of the dustbin (20) becomes dry, so that the growth of mold and pests can be suppressed.

[0066] When the heat generator (100) is coupled to the cleaner body (10), the cleaner motor (62) can operate at a low rotation speed so that air heated to 50°C or higher in the heat generator (100) can be introduced into the dust bin (20) without being cooled. When the suction nozzle (11) is coupled to the cleaner body (10), the cleaner motor (62) can operate at a high rotation speed to suck foreign substances on the surface to be cleaned into the dust bin (20). When the heat generator (100) is coupled to the cleaner body (10), the purpose is to introduce high-temperature air heated by the heat generator (100) into the dust bin (20), and therefore, the cleaner motor (62) can operate at a low rotation speed. When the vacuum cleaner motor (62) operates at a high rotation speed, the air may be introduced into the dust bin (20) before being heated to 50°C or higher in the heat generator (100), or the air heated to 50°C or higher may be cooled in the process of moving at a high speed, or the heater (110) of the heat generator (100) may be cooled by the air. In other words, even if the heat generator (100) operates, air at a temperature of 50°C or higher may not be introduced into the dust bin (20). Therefore, in order to supply high-temperature air into the dust bin (20), the vacuum cleaner motor (62) may be operated at a rotation speed lower than the rotation speed of the vacuum cleaner motor (62) when the suction nozzle (11) is coupled to the vacuum cleaner body (10). In other words, when the suction nozzle (11) is coupled to the cleaner body (10), the cleaner motor (62) can rotate at a first rotation speed or higher, and when the heat generator (100) is coupled to the cleaner body (10), the cleaner motor (62) can rotate at a second rotation speed or lower than the first rotation speed.

[0067] The vacuum cleaner (2) may include a control unit (60, FIG. 21) provided to control the on / off and rotation speed of the vacuum cleaner motor (62). The control unit (60) may be provided in the vacuum cleaner body (10). The control unit (60) may be connected to a body connector (61). When the suction nozzle (11) is coupled to the vacuum cleaner body (10), the control unit (60) may control the vacuum cleaner motor (62) to rotate at a first rotation speed or higher. When the heat generator (100) is coupled to the vacuum cleaner body (10), the control unit (60) may control the vacuum cleaner motor (62) to rotate at a second rotation speed or lower than the first rotation speed.

[0068] According to one embodiment, the heat generator (100) and the cleaner motor (62) can operate by receiving power from the battery (16) of the cleaner (2). The heat generator (100) and the cleaner motor (62) can operate by receiving power from the battery (16) even when the cleaner (2) is not connected to an external power source. Even when the cleaner body (10) is placed on a stand or docking station (3) and the battery (16) is being charged, the heat generator (100) and the cleaner motor (62) can operate by receiving power from the battery (16).

[0069] Figure 5 shows a cross-section of the vacuum cleaner shown in Figure 2.

[0070] Referring to Fig. 5, when a heat generator (100) is combined with a vacuum cleaner body (10), the air flow path moving from the heat generator (100) to the dust bin (20) will be described.

[0071] When the heat generator (100) is coupled to the cleaner body (10), as described above, the cleaner motor (62) can operate at a low rotational speed. The low rotational speed of the cleaner motor (62) may mean a rotational speed at which the air heated by the heat generator (100) can generate an air flow rate that can maintain a temperature of 50°C or higher to the dust bin (20). As described above, when the heat generator (100) is coupled to the cleaner body (10), the rotational speed of the cleaner motor (62) may be lower than the rotational speed of the cleaner motor (62) when the suction nozzle (11) is coupled to the cleaner body (10).

[0072] Referring to Fig. 2, air introduced into the inlet (131) of the heat generator (100) can be heated as it passes through the heater (110). The air heated as it passes through the heater (110) can be discharged through the outlet (143) of the heat generator (100). The outlet (143) is connected to the second opening (152a) formed at the other end (152) of the coupling portion (150), so that the outlet (143) and the second opening (152a) can substantially refer to the same opening. The air introduced into the second opening (152a) of the coupling portion (150) can be discharged through the first opening (151a) formed at one end of the coupling portion (150). The air discharged through the first opening (151a) can move upward along the flow path (30a) inside the extension pipe (30). Air passing through the path (30a) inside the extension pipe (30) can be introduced into the vacuum cleaner body (10). Air introduced into the vacuum cleaner body (10) can be introduced into the dust bin (20).

[0073] Through the above process, the air heated in the heat generator (100) can be introduced into the dust bin (20) through the extension pipe (30). As illustrated in FIG. 4, when the heat generator (100) is directly coupled to the cleaner body (10), the air passing through the inlet (131), the outlet (143), the second opening (152a), and the first opening (151a) of the heat generator (100) can be introduced directly into the cleaner body (10). The air introduced into the cleaner body (10) can be introduced into the dust bin (20). When the heat generator (100) is directly coupled to the cleaner body (10), the path through which the heated air moves can be simplified and shortened since it does not pass through the extension pipe (30).

[0074] Figure 6 illustrates a heat generator according to one embodiment. Figure 7 illustrates the heat generator illustrated in Figure 6 from another angle. Figure 8 illustrates an exploded view of the heat generator illustrated in Figure 6.

[0075] Referring to FIG. 6, a heat generator (100) according to one embodiment may include a heater case (120) configured to accommodate a heater (110), and a coupling portion (150) configured to be coupled to the other end (32) of the cleaner body (10) or the extension tube (30) and connected to the heater case (120).

[0076] A heater (110) configured to convert electric power into heat may be provided inside the heater case (120). There is no limitation on the type of heater (110), but for example, the heater (110) may include a fin tube heater provided with a plurality of fins (111) to expand the heat exchange area.

[0077] The heater case (120) can form an inlet (131) through which air is drawn in, and an outlet (143) through which air is discharged. Air drawn into the heater case (120) through the inlet (131) of the heater case (120) can be heated by the heater (110) and then discharged to the outside of the heater case (120) through the outlet (143).

[0078] The heater case (120) may include one inlet (131) as illustrated in FIG. 7. Alternatively, the heater case may include multiple inlets. In one embodiment, the heat generator may include a filter positioned to cover the inlet.

[0079] The heater case (120) may include a heater cover (130) having an inlet (131) formed therein, a case (141) having a receiving space (142) provided to receive the heater (110) and an outlet (143) formed therein. The case (141) may be provided in the form of a box with one side open. The heater cover (130) may be coupled to the case (141) to cover the open side of the case (141).

[0080] An exhaust port (143) may be formed on the other side of the case (141) located opposite the open side of the case (141). An accommodation space (142) may be formed between one side of the case (141) and the other side of the case (141).

[0081] According to one embodiment, the heat generator (100) may further include a control circuit (101, FIG. 21) configured to control the on / off and output of the heater (110). The heat generator (100) may further include a temperature sensor (102, FIG. 21) configured to measure the temperature inside the heat generator (100). The control circuit (101) may be connected to the heater (110), the temperature sensor (102), and the connector (153). The control circuit (101) may be configured to receive the temperature measured by the temperature sensor. The control circuit (101) may turn off the heater (110) when the temperature measured by the temperature sensor exceeds a preset value. Through this, a fire that may occur due to the heater (110) overheating may be prevented in advance.

[0082] The heat generator (100) may further include a bimetal that is configured to bend as the temperature increases. The bimetal may be configured to contact at least one of the positive terminal (113) and the negative terminal (112) of the heater (110). When the temperature of the heater (110) exceeds a predetermined value, the bimetal may bend, thereby cutting off the power supply to the heater (110). This may prevent a fire that may occur due to overheating of the heater (110).

[0083] The case (140) may further include a circuit receiving portion (144) provided to receive a control circuit (101) configured to control the heater (110), and a circuit cover (145) provided to cover the circuit receiving portion (144).

[0084] The heat generator (100) may include a coupling part (150) that is provided to be detachably coupled to the other end (32) of the cleaner body (10) or the extension pipe (30). The coupling part (150) may be connected to the heater case (120). The coupling part (150) may include one end (151) that is provided to be coupled to the other end (32) of the cleaner body (10) or the extension pipe (30), and the other end (152) that is provided to be connected to the heater case (120). The one end (151) of the coupling part (150) may be referred to as a first coupling part (151), and the other end (152) of the coupling part (150) may be referred to as a second coupling part (152). A first opening (151a) may be formed in the first coupling part (151). A second opening (152a) may be formed in the second connecting portion (152).

[0085] In a heat generator (100) according to one embodiment, the inlet (131), the outlet (143), the other end (152) of the coupling portion (150), and one end (151) of the coupling portion (150) may be arranged on a straight line (L1). Through this, air introduced into the interior of the heat generator (100) may be discharged to the outside of the heat generator (100) through the straight path.

[0086] A connector (153) may be provided at the first coupling portion (151). The connector (153) may be provided to be electrically connected by contacting the main body connector (61) of the cleaner main body (10) or the second extension tube connector of the extension tube (30). The connector (153) may be directly connected to the cleaner main body (10) or indirectly connected via the extension tube (30). The connector (153) may electrically connect the battery (16) and the heater (110) by being directly or indirectly connected to the cleaner main body (10). The heater (110) may receive power from the battery (16) via the connector (153). According to one embodiment, the connector (153) may electrically connect the battery (16) and the control circuit (101).

[0087] The connector (153) may include a positive terminal (153a) and a negative terminal (153b). The connector (153) may further include a communication terminal (153c). The positive terminal (153a) and the negative terminal (153b) may be connected to the positive terminal (113) and the negative terminal (112) of the heater (110), respectively. The communication terminal (153c) may be connected to the control circuit (101).

[0088] FIG. 9 illustrates the vacuum cleaner illustrated in FIG. 1 with the suction nozzle connected to the extension tube separated and a heat generator attached according to one embodiment. FIG. 10 illustrates the vacuum cleaner illustrated in FIG. 9 disassembled into the vacuum cleaner body, the extension tube, and the heat generator. FIG. 11 illustrates the vacuum cleaner illustrated in FIG. 9 with the extension tube separated from the vacuum cleaner body and the heat generator directly attached to the vacuum cleaner body.

[0089] The cleaner (2) of the cleaning device (1) according to one embodiment may include a heat generator (200) that is detachably coupled directly or indirectly to the cleaner body (10).

[0090] The heat generator (200) can be detachably coupled to the cleaner body (10). The heat generator (200) can be detachably coupled to an extension pipe (30). One end (31) of the extension pipe (30) can be detachably coupled to the cleaner body (10), and the heat generator (200) can be detachably coupled to the other end (32) of the extension pipe (30).

[0091] The heat generator (200) may be configured to heat air. When the heat generator (200) is coupled to the vacuum cleaner body (10), high-temperature air heated by the heat generator (200) may be introduced into the dust bin (20). When the heat generator (1200) is coupled to the vacuum cleaner body (10), the heat generator (200) may be powered by the battery (16) of the vacuum cleaner (2). The heat generator (200) may be operated by receiving power from the battery (16) of the vacuum cleaner (2).

[0092] The heat generator (200) can heat air to 50°C or higher. The heat generator (200) can heat air to 50°C or higher to eliminate pests. For example, the heat generator (200) can heat air introduced into the heat generator (200) to 50°C to 80°C.

[0093] When the heat generator (200) and the vacuum cleaner motor (62) operate, high-temperature air heated by the heat generator (200) by the suction force generated by the vacuum cleaner motor (62) can be introduced into the dust bin (20). The high-temperature air may refer to air heated to 50°C or higher by the heat generator (200).

[0094] When the heat generator (200) is coupled to the cleaner body (10), the cleaner motor (62) can operate at a low rotation speed so that air heated to 50°C or higher in the heat generator (200) can be introduced into the dust bin (20) without being cooled. When the suction nozzle (11) is coupled to the cleaner body (10), the cleaner motor (62) can operate at a high rotation speed to suck foreign substances on the surface to be cleaned into the dust bin (20). When the heat generator (200) is coupled to the cleaner body (10), the purpose is to introduce high-temperature air heated by the heat generator (200) into the dust bin (20), and therefore, the cleaner motor (62) can operate at a low rotation speed. When the vacuum cleaner motor (62) operates at a high rotation speed, the air may be drawn into the dust bin (20) before being heated to 50°C or higher in the heat generator (100), or the air heated to 50°C or higher may be cooled in the process of moving at a high speed, or the heater (210) of the heat generator (200) may be cooled by the air. In other words, even if the heat generator (200) operates, air at a temperature of 50°C or higher may not be drawn into the dust bin (20). Therefore, in order to supply high-temperature air into the dust bin (20), the vacuum cleaner motor (62) may be operated at a rotation speed lower than the rotation speed of the vacuum cleaner motor (62) when the suction nozzle (11) is coupled to the vacuum cleaner body (10). In other words, when the suction nozzle (11) is coupled to the cleaner body (10), the cleaner motor (62) can rotate at a first rotation speed or higher, and when the heat generator (200) is coupled to the cleaner body (10), the cleaner motor (62) can rotate at a second rotation speed or lower than the first rotation speed.

[0095] The vacuum cleaner (2) may include a control unit (60) configured to control the on / off and rotation speed of the vacuum cleaner motor (62). When the suction nozzle (11) is coupled to the vacuum cleaner body (10), the control unit (60) may control the vacuum cleaner motor (62) to rotate at a first rotation speed or higher. When the heat generator (200) is coupled to the vacuum cleaner body (10), the control unit (60) may control the vacuum cleaner motor (62) to rotate at a second rotation speed or lower, which is lower than the first rotation speed.

[0096] Fig. 12 illustrates a cross-section of the vacuum cleaner illustrated in Fig. 9. Referring to Fig. 12, the air flow path when the heat generator (200) is coupled to the vacuum cleaner body (10) will be described.

[0097] Referring to Fig. 12, air introduced through a plurality of holes (233) of a heat generator (200) can be heated by a heater (210). The air heated by the heater (210) can be discharged to an exhaust port (236) through a guide path (234a) formed by a guide duct (234) and a connection path (235a) formed by a connection duct (235). Since the exhaust port (236) is connected to a second opening (252a) formed at the other end (152) of the coupling portion (250), air discharged to the exhaust port (236) can be introduced into the second opening (252a). Air introduced into the second opening (252a) of the coupling portion (250) can be discharged through the first opening (251a) of the coupling portion (250). Air discharged through the first opening (251a) can move upward along the flow path (30a) inside the extension pipe (30). Air passing through the flow path (30a) inside the extension pipe (30) can be introduced into the vacuum cleaner body (10). Air introduced into the vacuum cleaner body (10) can be introduced into the dust bin (20).

[0098] Through the above process, the air heated in the heat generator (200) can be introduced into the dust bin (20) via the extension pipe (30). As illustrated in FIG. 11, when the heat generator (200) is directly coupled to the cleaner body (10), the air passing through the plurality of holes (233), the exhaust port (236), the second opening (252a), and the first opening (251a) of the heat generator (200) can be introduced directly into the cleaner body (10). The air introduced into the cleaner body (10) can be introduced into the dust bin (20). When the heat generator (200) is directly coupled to the cleaner body (10), the path through which the heated air moves can be simplified and shortened since it does not pass through the extension pipe (30).
