Description
- 1. Field of the Invention
- This invention relates to a steam cleaner, particularly to one moved forward to clean floor with steam at first and then brushing and cleaning with a rotating disc with help of steam synchronously, performing washing, sterilizing, and brushing.
- 2. Description of the Prior Art
- Conventional mops are widely used for cleaning, but they cannot completely clean out dirt in small crevices or gaps in floors, and they have to be washed clean after cleaning a certain dimensions of a floor so as to use it again, not so convenient and even troublesome to use.
- So conventional cleaning machines have been thought out, using a detergent and a cleaning unit together for thoroughly cleaning floors. For example, a U.S. Pat. No. 6,247,202 B1 titled “Cleaning machine” includes a supply box of a detergent, a detergent dispenser for dispensing detergent on the floor, a main guide tube connected between the supply box and the dispenser for detergent to flow from the supply box to the dispenser, an auxiliary guide tube connected also between the supply box and the dispenser for guiding detergent from the supply box to the dispenser, a main valve to be opened and closed to control detergent flowing in the main guide tube, an auxiliary valve to be used for controlling detergent flowing in the auxiliary guide tube, a main remote controller connected to and controlling the main valve in its opening and closing, and an auxiliary remote controller connected to and controlling the auxiliary valve in its opening and closing, Thus the main and the auxiliary valves are opened and closed to control a first detergent and a second detergent to flow through the main and the auxiliary guide tube from the supply box to the dispenser so as to carry out cleaning work.
- However, the cleaning machine of the U.S. patent just described has the following disadvantages in practical use.
- 1. A handle and a foot base are provided firmly, unable to move, so the handle cannot be adjusted in its height to suit to the height of a user, And in moving the cleaning machine, a user has to move together with the moving machine in the same direction. In other words, a user must follow the movement of the machine, resulting in inconvenience and embarrassment.
- 2. When the machine is not used, only rear wheels, permitting the machine prone to slide down if the floor is not flat, impossible to be positioned for storing, support the machine. Should the brush be also used to support the machine, the brush might disfigure owing to the heavy weight of the machine, wording its function in the future work.
- 3. The cleaning machine can be only used with detergent in cleansing and sterilizing floors, not so convenient to use, and use of detergent may mean pollution to the environment and potent slipping of a user as well.
- This invention has been devised to offer a steam cleaner improved in the disadvantages of the conventional cleaning machine described above.
- The feature of the invention is a water pump controlled to send water stored in a water tank into a heater, which heats up the water to become steam to be shot out of shoot holes of a base. Meanwhile a water volume button is used to control the operative frequency of the water pump to change the volume of steam to be shot out. Further, a switch button is provided on a handle to move a side plate via a connect rod to star and control operative conditions of the steam cleaner, In addition, The handle is pivotally connected with the base so that the handle can be inclined to one of numerous angles to suit to the height of a user in handling the steam cleaner. When the steam cleaner is not used, it can be placed on a support base for storing away.
