Description

Description STEAM CLEANER
Technical Field
[1] The present invention relates to a steam cleaner, and more particularly to a steam cleaner, which can control the quantity of steam sprayed from the cleaner based on the movement of the cleaner.
[2]
Background Art
[3] In general, the cleaning at home progresses with an initial job of removing dust on a floor using a broomstick or a vacuum cleaner, and a finishing job of removing foreign substances, such as concentrated dirt, oil, or the like, using a wet mop in sequence.
[4] In the finishing cleaning job using the wet mop, the maintenance of an appropriate level or more of moisture is required in order to maintain a certain level of ability capable of removing the foreign substances, so that the mop is necessary to be often soaked in water and squeezed. Then, the wet mop itself provides an environment suitable for growth of any microorganisms, including various bacteria. Therefore, if the mop is not additionally sterilized, it is considerably unhygienic.
[5] Further, the concentrated dirt and oil are not easily removed by the common wet mop so that it is necessary to repeatedly scrub the dirt and oil several times. In order to improve the problems, conventionally, by soaking the wet mop in hot water, it is effective to remove some degrees of the polluted substances. However, the cleaning becomes troublesome, and thus that is not a fundamental solution.
[6] Recently, in order to solve the above troublesomeness, the steam cleaner developed for cleaning use in general homes has now prevailed.
[7] The steam cleaner sprays high-temperature steam to a polluted part of an object requiring cleaning, and changes the properties of the polluted substances, such as the concentrated dirt or oil, to be easily removed from the polluted part through melting or revitalizing them, so that the effect of the cleaning is increased and efforts put forth by a worker can be remarkably decreased.
[8] Further, the high-temperature steam is directly supplied to a mop attached to the steam cleaner, so that the sterilization is continuously performed during the cleaning which is contaminated by a pollutant. Therefore, the propagation of bacteria or the like can be interrupted, thereby further providing a preferable effect on hygiene.
[9] The conventional steam cleaner mainly includes a water tank for supplying water, a steam generation apparatus having a built-in electric heater and generating steam by heating water by the built-in electric heater, and a pump mounted on a pipeline connecting the steam generation apparatus with the water tank and supplying water of the water tank to the steam generation apparatus. Further, the conventional steam cleaner has a structure in which an electric power is applied by a switch operation, the built-in electric heater of the steam generation apparatus is heated so as to generate steam, and steam passes through the mop so that steam can be sprayed to the polluted part requiring the cleaning.
[10] In the conventional steam cleaner, the quantity of steam is always constant and the temperature of steam is considerably high. Therefore, there is a worry that a thermal deformation may occur on a floor surface or on a floor paper if the steam cleaner is left without movement during at least a predetermined time interval. Further, in this case, there arises a problem in that steam passing through the mop is re-condensed so that the residual water remains on the floor surface.
[H]
Disclosure of Invention Technical Problem
[12] Therefore, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a steam cleaner which interrupts the generation of steam if motion is not detected during the cleaning, and controls the quantity of sprayed steam according to a change of a movement speed.
[13]
Technical Solution
[14] In accordance with an aspect of the present invention, there is provided a steam cleaner including: a power switch; a water tank for supplying water; a steam generation apparatus for generating steam by heating water by a built-in electric heater mounted in the steam generation apparatus; a flow rate control pump mounted on a pipeline connecting the steam generation apparatus with the water tank and controlling quantity of water supplied to the steam generation apparatus; a motion detection sensor for detecting motion and movement speed; and a controller electrically connected with the electric heater, the flow rate control pump, and the motion detection sensor, the controller outputting a signal to control the electric heater and the flow rate control pump according to information detected by the motion detection sensor.
[15] In accordance with another aspect of the present invention, there is provided a steam cleaner in which the controller interrupts electric power supplied to the electric heater and outputs a signal stopping the flow rate control pump if the motion detection sensor detects that there is no motion.
[16] In accordance with a further aspect of the present invention, there is provided a steam cleaner in which the controller outputs a signal controlling a current supplied to the electric heater and a discharge flow rate of the flow rate control pump, proportional to the movement speed detected by the motion detection sensor.
Advantageous Effects
[17] According to the present invention as described above, even when an inventive steam cleaner is left without movement during its operation, the steam cleaner prevents continuous spraying of steam, which may be re-condensed and then remain as residual water on the floor, and prevents accumulative heat radiation, which may cause permanent deformation on floor paper, etc. Further, the steam cleaner according to the present invention can spray an appropriate quantity of steam depending on the movement speed during the cleaning, so as to prevent local generation of residual water when the cleaner moves at a low speed and to prevent the quantity of steam from lacking when the cleaner moves at a high speed, thereby maximizing the effect of the cleaning.
[18]
Brief Description of the Drawings
[19] The foregoing and other objects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawing in which:
[20] FIG. 1 is a diagram schematically illustrating a steam cleaner according to an exemplary embodiment of the present invention.
[21]
Mode for the Invention
[22] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
[23] FIG. 1 is a diagram schematically illustrating a steam cleaner according to an exemplary embodiment of the present invention.
[24] As shown in FIG. 1 , the steam cleaner according to the present invention basically includes a power switch, a water tank 10 for supplying water, and a steam generation apparatus 30 having a built-in electric heater 35 and generating steam by heating water by the built-in electric heater 35, a flow rate control pump 20 mounted on a pipeline connecting the steam generation apparatus 30 with the water tank 10 and controlling the quantity of water supplied to the steam generation apparatus 30, a motion detection sensor for detecting motion and movement speed, and a controller electrically connected with the electric heater 35, the flow rate control pump 20, and the motion detection sensor and outputting a signal to control the electric heater 35 and the flow rate control pump 20 according to information detected by the motion detection sensor.
[25] If the motion detection sensor detects that there is no motion, the controller interrupts the electric power supplied to the electric heater 35 and outputs a signal which stops an operation of the flow rate control pump 20.
[26] Further, the controller outputs a signal controlling a current supplied to the electric heater 35 and a supplying flow rate of the flow rate control pump 20 proportional to the movement speed detected by the motion detection sensor.
[27] In particular, first, the motion detection sensor detects if the steam cleaner moves for cleaning use when the power switch turns on, second, if it does, the motion detection sensor detects a degree of the movement speed.
[28] Therefore, if the motion detection sensor detects that the steam cleaner is in a still state without motion during the period when the electric power is applied through the power switch, the motion detection sensor transfers such information to the controller, and the controller outputs the signal interrupting the electric power applied to the electric heater 35 in order to interrupt the generation of steam, and additionally outputs the signal stopping the flow rate control pump 20 in order to interrupt the water supplied from the water tank 10 to the steam generation apparatus 30.
[29] Meanwhile, the controller controls the quantity of steam sprayed depending on the movement speed during moving the steam cleaner. That is, in a state that information on the optimum quantity of steam required depending on the movement speed of the steam cleaner is previously input to the controller, the controller receives information on the movement speed detected from the motion detection sensor, outputs the signal controlling the current applied to the electric heater 35, and controls the quantity of the heat radiated from the electric heater 35. Additionally, the controller outputs a signal controlling a discharge flow rate of the flow rate control pump 20, and controls the quantity of the supplied water, so that the quantity of the sprayed steam generated in the steam generation apparatus 30 can be controlled.
[30] As a matter of course, it is apparent that if the movement speed of the steam cleaner is high, a large quantity of steam is necessary, whereas if the movement speed of the steam cleaner is low, a small quantity of steam is necessary. That is, proportional to the movement speed, the quantity of the heat radiated from the electric heater 35 and the quantity of the water supplied from the water tank 10 are controlled, so that the optimum quantity of steam can be generated and sprayed.
[31]
Industrial Applicability
[32] According to the present invention as described above, even when an inventive steam cleaner is left without movement during its operation, the steam cleaner prevents continuous spraying of steam, which may be re-condensed and then remain as residual water on the floor, and prevents accumulative heat radiation, which may cause permanent deformation on floor paper, etc. Further, the steam cleaner according to the present invention can spray an appropriate quantity of steam depending on the movement speed during the cleaning, so as to prevent local generation of residual water when the cleaner moves at a low speed and to prevent the quantity of steam from lacking when the cleaner moves at a high speed, thereby maximizing the effect of the cleaning. [33] Although several exemplary embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
