- Embodiments also provide a nozzle for a cleaner, which is designed such that a water tank is detachably provided in a steam generating unit and thus the water tank can be cleaned if needed.
- The objects are solved by the features of the independent claim. According to one example, a nozzle for a cleaner includes: a nozzle main body defining an exterior of the nozzle; and a steam generating unit provided in the nozzle main body and generating steam using water, wherein the steam generating unit includes: a water tank storing the water and having a tank cap that is selectively opened; a heating unit receiving the water from the water tank and heating the received water; and a water reservoir supplying the water from the water tank to the heating unit, wherein the water is introduced into the water reservoir unit internal pressure maintains a balance between the water tank and the water reservoir.

Fig. 3 is a perspective view of a steam generating unit according to an embodiment,Fig. 4 is an exploded perspective view of the steam generating unit ofFig. 3 , andFig. 5 is a top plane view of the steam generating unit ofFig. 3 . - Referring to
Figs. 3 through 5 , thesteam generating unit 100 of an embodiment includes awater tank 110 for storing the water supplied, awater reservoir 130 that is provided at a side of thewater tank 110 and stores a predetermined amount of the water supplied from thewater tank 110, and aheating unit 150 provided at a side of thewater reservoir 130 and generating the steam by heating the water supplied from thewater reservoir 130. - In more detail, the
water tank 110 may be formed in a roughly a rectangular parallelepiped shape. A water storage space is defined in thewater tank 110. - The
water tank 110 is provided at a bottom thereof with anopening 112 through which the water stored in thewater tank 110 is directed to thewater reservoir 130. - Further, the bottom of the
water tank 110 is inclined downward toward theopening 112. Accordingly, the water stored in thewater tank 110 can be effectively directed toward theopening 112. - The
tank opening 112 is provided with atank cap 120 for selectively closing theopening 112. Thetank cap 120 extends toward an interior of thewater reservoir 130. - In more detail, the
tank cap 120 includes avalve member 122 adjusting the supply of the water from thewater tank 110 to thewater reservoir 130 and aguide unit 123 for guiding movement of thevalve member 122. - The water is detachably provided from the

steam generating unit 100 includes aseating plate 116 on which the water tank 110 seats. Theseating plate 116 may be disposed at an identical plane to the top surface of thewater reservoir 130.Fig. 3 illustrates a state immediately before thewater tank 110 seats on theseating plate 116. - In addition, the
seating plate 116 is provided with a fixingportion 117 for fixing thewater tank 110 seating thereon. The fixingportion 117 may be provided in the form of a groove. - The
water tank 110 is provided with a fixingprotrusion 119 that is designed to be capable of locking with the fixingportion 117. The fixingprotrusion 119 is bent to having a -shape. - The fixing
protrusion 119 is inserted into the fixingportion 117 in the course of seating thewater tank 110 in theseating plate 116. The fixingprotrusion 119 may be an elastic member. In this case, the fixingprotrusion 119 may be elastically deformed during the coupling or separation of thewater tank 110. - Further, a
first leg 118 supporting thewater tank 110 is provided under theseating plate 116. A plurality of thefirst legs 118 may be provided to correspond corners of theseating plate 116. - Further, the water reservoir is formed in a roughly a rectangular parallelepiped shape. A size and volume of the
water reservoir 130 may be less than those of thewater tank 110. Asecond leg 138 for supporting thereservoir 130 is provided under thewater reservoir 130. - The
water reservoir 130 is provided with anopening 132 through which the water is supplied from thewater tank 110. Thereservoir opening 132 may be larger than that of thetank opening 112. - As the
reservoir opening 132 is larger than that of thetank opening 112, thetank cap 120 can easily extend from a portion under thetank opening 112 toward the interior of thewater reservoir 130. - Further, the
water reservoir 130 is provided with aconflicting portion 135 mutually acting with thetank cap 120. Theconflicting portion 135 protrudes upward from an inner bottom surface of thewater reservoir 130. - Further, the
water reservoir 130 is provided with anexternal air inlet 137 through which external air is introduced. When the air is introduced through theexternal air inlet 137, the interior of thewater reservoir 130 maintains the atmospheric pressure. - A sealing
member 114 is provided between thewater tank 110 and thewater reservoir 130 to prevent the water from leaking from thewater reservoir 130. The sealingmember 114 is disposed along an outer circumference of thewater reservoir opening 132. - The
heating unit 150 for heating the water introduced into thewater reservoir 130 is provided at a side of thewater reservoir 130. - The
heating unit 150 may be formed in a roughly a rectangular parallelepiped shape. Aheater 151 generating the steam by heating the water is provided in theheating unit 150. Theheater 151 may be disposed on a bottom of theheating unit 150. Here, theheater 151 may be a sheath heater, a PTC heater, a ceramic heater, or the like. - Although not shown in the drawings, a felt may be provided under the
heater 151 to prevent the heat generated by theheater 151 from being transferred to a surface of theheating unit 150. That is, the felt may be referred to as a heat transfer preventing member. - The felt may be disposed to surround the
heater 151. - Further, a
heater coupling portion 154 to which theheater 151 is coupled is formed on a side surface of theheating unit 150. A side of theheater 151 may be coupled to theheater coupling portion 154. - In addition, the
heating unit 150 is provided with asteam outlet 155 through which the generated steam is discharged. Thesteam outlet 155 is provided in the form of a pipe, a portion of which extends into theheating unit 150 and the rest of which protrudes to the external side. - That is, the
steam outlet 155 is fitted through a surface of theheating unit 150. Needless to say, thesteam outlet 155 is fixed on the surface of the heating unit 1550. - Further, the
steam outlet 155 is disposed on an upper portion of theheating unit 150. In more detail, thesteam outlet 155 may be disposed at a higher location than a central portion of theheating unit 150. This is because that the steam generated by theheater 151 is lighter than the water and thus intends to rise. - As shown in
Fig. 5 , a plurality ofsteam outlets 155 may be provided. - Meanwhile, an
inlet 136 through which the water is introduced from thewater reservoir 130 to theheating unit 150 is formed between thewater reservoir 130 and theheating unit 150. As shown inFig. 5 , one ormore inlets 136 may be formed on a side of thewater reservoir 130. - In order to easily direct the water from the
water reservoir 130 to theheating unit 150, theinlet 136 may be inclined downward toward theheating unit 150. That is, an undersurface of thewater reservoir 130 is located at a higher position than an undersurface of theheating unit 150. - The following will describe a steam generating process by the
steam generating unit 100. -
Fig. 6 is a cross-sectional view of the steam generating unit. - Referring to
Fig. 6 , the water stored in thewater tank 110 may be introduced into thewater reservoir 130 through thetank opening 112. During this process, thevalve member 122 of thetank cap 120 is opened. This will be described in more detail with reference to the accompanying drawings. - Further, the water stored in the
water reservoir 130 is introduced into theheating unit 150 through theinlet 136. - The water in the
water tank 110 may be introduced into theheating unit 150 through thewater reservoir 130 according to Pascal's principle. - According to the Pascal's principle, pressure applied to fluid contained in an enclosed container is transferred from all portion of the fluid to a wall of the container without being reduced.
-
- The formula (1) shows that pressure maintains a balance between the
water tank 110 and thewater reservoir 130. The pressure of thewater tank 110 is a sum of vacuum pressure in the tank and pressure by the water stored in the tank. The pressure of thewater reservoir 130 is a sum of air pressure in thereservoir 130 and pressure by the water stored in thewater reservoir 130. As described above, the air pressure in the reservoir remains as the atmospheric pressure. - When the
tank cap 120 is opened, the water in thewater tank 110 falls down to thewater reservoir 130 by gravity, i.e., by water pressure. During this process, the air in thewater reservoir 130 is introduced into thewater tank 110 through thetank cap 120. - That is, when the water falls down to the
water reservoir 130, a water level of thewater reservoir 130 reaches to a predetermined level h1. - After the above, as the water level of the
water reservoir 130 increases and thus the water in thewater reservoir 130 covers at least partly thetank cap 120, the air in thewater reservoir 130 cannot be introduced into thewater tank 110 through thetank cap 120. - That is, when the
water reservoir 130 increases to a water level h2, the water covers a lower opening of thetank cap 120, i.e., a water level determining portion 125 (seeFig. 7 ) and thus the air in thewater reservoir 130 cannot be introduced into thewater tank 110. - At this point, vacuum pressure is formed in the
water tank 110. - In brief, the water level h2 means a height corresponding to the lower opening of the
tank cap 120, i.e., the waterlevel determining portion 125. - In this state, the internal pressure of the
water tank 110 becomes a sum of the vacuum pressure and water pressure by the water level and the internal pressure of thewater reservoir 130 becomes a sum of the atmospheric pressure and the water pressure by the water level. That is, pressure maintains a balance between thewater tank 110 and thewater reservoir 130. - The formula (2) shows that the pressure maintains a balance between the
water tank 110 and thewater reservoir 130. The internal pressure of theheating unit 150 becomes a sum of the pressure by the water in theheating unit 150 and steam/air pressure in theheating unit 150. - That is, when there is no water in the
heating unit 150 or there is a small amount of water in the heating unit, the water flows from thereservoir 130 to theheating unit 150 by a water level difference between thereservoir 130 and theheating unit 150. - Accordingly, the water level of the
heating unit 150 may be determined by the water level of thewater reservoir 130. - In brief, as the water stored in the
water reservoir 130 flows to theheating unit 150 unit, theheating unit 150 has a same water level as thewater reservoir 130. That is, when theheating unit 150 has the same water level as thewater reservoir 130, no water flows to theheating unit 150. - By the above-described structure, the water in the
water tank 110 can effectively flow to theheating unit 150. That is, there is no need for a pump or controller that can direct the water to the heating unit. Therefore, the water can be directed from the water tank to theheating unit 150 by the structure. - An operation and structure of the
tank cap 120 that selectively directs the water from thewater tank 110 to thewater reservoir 130 will be described hereinafter with reference to the accompanying drawings. -
Figs. 7 and8 are views of the tank cap according to an embodiment,Fig. 9 is a view illustrating a coupling structure of the water tank and the tank cap according to an embodiment, andFig. 10 is a view illustrating an operation of the tank cap ofFigs. 7 and8 . - Referring to
Figs. 7 through 10 , thetank cap 120 according to an embodiment includes acap body 121 defining an exterior of thetank cap 120, avalve member 122 that is provided above thecap body 121 and is selectively opened, aguide unit 123 for guiding movement of thevalve member 122, and aspring 124 biasing theguide unit 123. - In more detail, the
cap body 121 is provided with aninner unit 121a formed in an interior thereof and anouter unit 121b formed on an outer side of theinner unit 121a. The inner andouter units - The
inner unit 121a is provided with opened top and bottom. Therefore, the water is directed from the upper end of thecap body 121 and discharged to thewater reservoir 130 through the lower end of thecap body 121. - The
outer unit 121b is designed to have a larger diameter than theinner unit 121a. That is, at least a portion of theinner unit 121a is received in theouter unit 121b. - Further, the
outer unit 121b is provided at an inner circumference thereof with athread 121e by which thetank cap 120 can be easily coupled to thewater tank 110. - Further, the
water tank 110 is provided with a coupling portion 117 (seeFig. 9 ) coupled to thethread 121e. The coupling portion extends from an undersurface of thewater tank 110 downward. Further, thecoupling portion 117 is provided with ascrew portion 117a screw-coupled to thethread 121e. - A receiving
space 121d grooved in a lower portion of theinner unit 121a to receive at least a portion of theguide unit 123. Theguide unit 123 moves in a vertical direction in the receivingspace 121d. - Further, the water
level determining portion 125 is formed on a top of the receivingspace 121d to determine the water level of thewater reservoir 130. The waterlevel determining portion 125 is opened so that the water and air can pass therethrough. - The water
level determining portion 125 is a location through which the water starts being discharged from thetank cap 120. The waterlevel determining portion 125 has a corresponding height to the maximum water level h2. That is, when the water level of thewater reservoir 130 is higher than the waterlevel determining portion 125, the air in thewater reservoir 130 cannot be directed to thewater tank 110 through the waterlevel determining portion 125. - That is, the water
level determining portion 125 defines a maximum water level of thewater reservoir 130. - Further, when the air is not introduced into the
water tank 110, the water in thewater tank 110 cannot be introduced into thewater reservoir 130. - Meanwhile, the
guide unit 123 is movably provided in theinner unit 121a. Theguide unit 123 is provided in the form of a bar extending in a vertical direction. - A supporting
protrusion 123a allowing theguide unit 123 to be supported on theinner unit 121a is formed on an approximately central portion of theguide unit 123. Theinner unit 121a is provided at a location corresponding to the supportingprotrusion 123a with a supportingunit 121c. The supportingprotrusion 123a is supported on a top of the supportingunit 121c. - As the supporting
protrusion 123a is supported on the supportingunit 121c, the separation or deformation of theguide unit 123 can be prevented. - Further, the
valve member 122 is fixed on an upper portion of theguide unit 123. Thevalve member 122 may be fitted around theguide unit 123. - The coupling of the
guide unit 123 and thevalve member 122 is not specifically limited. For example, thevalve member 122 may be coupled to theguide unit 123 by a coupling member or by a shrink-fitting manner. - Meanwhile, a
conflict responding unit 123b mutually acting with theconflict portion 135 is provided on a lower end of theguide unit 123. Here, thecounter-conflicting unit 123b is formed at a corresponding location to theconflicting portion 135. - In the course of coupling the
water tank 110 to thewater reservoir 130, theconflicting portion 135 closely contacts thecounter-conflicting unit 123b to bias thecounter-conflicting unit 123b. - Further, when the
water tank 110 is completely coupled to thewater reservoir 130, thecap body 121 is lowered to a predetermined location but theguide unit 123 and thecounter-conflicting unit 123b are restricted by theconflicting portion 135. - During the above process, the
spring 124 provided on theguide unit 123 is compressed. At this point, the supportingunit 121c moves in a direction in which thespring 124 is compressed, i.e., in a downward direction, and thus the supportingprotrusion 123a moves away from the supportingunit 121c. - Meanwhile, the
spring 124 is provided around theguide unit 123 to bias theguide unit 123. Thespring 124 has a first end fixed on thecounter-conflicting unit 123b and a second end fixed on theinner unit 121a. - Further, the
inner unit 121a is provided with aspring fixing portion 121 fixing thespring 124. Thespring fixing portion 121f is formed on an undersurface of theinner unit 121a. - The
spring 124 is compressed and restored during the movement of theguide unit 123 in the vertical direction. - The following will describe an operation of the
tank cap 120 with reference toFig. 10 . - During the process for coupling the
water tank 110 to thewater reservoir 130, the lower end portion (i.e., thecounter-conflicting unit 123b) of thetank cap 120 closely contacts theconflicting portion 135. - Further, when the
water tank 110 is completely coupled to thewater reservoir 130, thecap body 121 moves downward to a predetermined location. However, theguide unit 123 is constricted by theconflicting unit 135 not to move downward as long as thecap body 121 moved downward. Thecounter-conflicting unit 123b maintains the close-contact state with theconflicting portion 135. - In addition, the
conflicting portion 135 applies reacting force F1 to thecounter-conflicting unit 123b, in the course of which thespring 124 is compressed and thevalve member 122 moves away from the top of thecap body 121 in a direction a. - Then, the upper end of the
cap body 121 is opened and the water in thewater tank 110 flows downward through the upper end of thecap body 121. In addition, the water is introduced into thewater reservoir 130 through the opened lower end of thecap body 121. - The following will describe an operation of the steam generating unit of the embodiment.
- First, the
water tank 110 is coupled to thetank cap 120. In this state, thevalve member 122 of thetank cap 120 closes thetank opening 112. - Further, the
water tank 110 seats on theseating plate 116 and is thus coupled to thewater reservoir 130. - Then, the
valve member 122 of thetank cap 120 spaces away from thecap body 121 and thus the water in thewater tank 110 is introduced into thewater reservoir 130 through thetank cap 120. - As the water is introduced into the
water reservoir 130, the water level of thewater reservoir 130 increases. When the water level of thewater reservoir 130 reaches to the water level h2, pressure maintains a balance between thewater tank 110 and thewater reservoir 130 and thus the water cannot be introduced into thewater reservoir 130. - Meanwhile, as the water level of the
water reservoir 120 increases, the water level of thewater reservoir 130 differs from that of theheating unit 150. The water in thewater reservoir 130 is introduced into theheating unit 150 through theinlet 136 in accordance with the water level difference. - The water introduced into the
heating unit 150 is heated by theheater 151, in the course of which the steam is generated and discharged to the external side through asteam outlet 155. - According to the above-described steam generating unit, since a relatively small amount of the water is introduced into the
heating unit 150, the heating time can be shortened. - Further, since the structure of the steam generating unit is simple, the weight of the nozzle in which the steam generating unit is provided can be reduced.
- 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 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.
- According to the embodiments, since a relatively small amount of water is supplied from the water reservoir to the heater, the steam generating time can be shortened and thus the industrial applicability is high.
