The present invention relates to a steam-cleanable vacuum cleaner.

Originally, vacuum cleaners have been developed for the Western stocking environment. When the vacuum sticking alone cannot easily remove the dirt attached to the living equipment such as carpets, the wet method of spraying steam or washing water is widely used. It has been adopted. This wet vacuum method has been widely used due to its high interest in well-being and high price. Although it is a little better than general vacuum cleaners in ondol floor living environment such as Korean living environment, the wet vacuum method optimized for western standing space using carpet floor still has many aspects that are not compatible with Korean ondol floor. Therefore, since the necessity of cleaning the mop along with the vacuum cleaning, many applications have been filed in Korea since around 1988. However, many technological developments have not found products that can satisfy the needs of consumers.

When the wet vacuum system is determined based on the technology described in the patent application as a prior art, it can be largely divided into a steam method and a normal temperature wet method, and the normal temperature wet method can be divided into several categories.

1. Room temperature wet method

1) Attach the mop separately from the suction area of the existing vacuum cleaner (usually the position not affected by suction)

 a. Stationary; Fasten wet mop by clip or fixture

 b. Lola formula; Rotation by pushing force and one-way rotation by ratchet gear

 c. Winder equation; Mop cloth or carriage wound on a two-axis winder

 d. Motor rotation; Brush or rag rotates horizontally

Classified as Mop and vacuum cleaner functions are merely physically combined, there is a problem that the management and replacement of the mop should continue.

2) with washing liquid or washing water spray type

 a. Non-power system; Cleaner tank is installed on the cleaner head body and sprayed in front of the cleaning surface by manual or pressing pressure

 b. Power system; Pumping spray of wash water by water pump (generally adopted for cleaning head and main body)

There is a way. Rubbing the cleaning solution with a brush or cotton in the suction area is almost a wet cleaning, which sacrifices the benefits of a vacuum cleaner that separates contaminants.

The wet vacuum cleaner, which does not attach a mop separately, is rubbed with a cleaning brush or a cleaning cloth while spraying the washing water, so it is easy to remove contaminants attached to the surface to be cleaned, but rather than to separate solid contaminants. It is disadvantageous.

2. Steam method

1) Steam injection method

In general, a steam tank is attached to the cleaner head, the steam is ejected to the bottom of the cleaner head through a nozzle, and a wet cloth is attached to the bottom surface of the cleaner head with a cleaning cloth. Some steam passes through the cleaning cloth, steams the surface to be cleaned, and some liquidizes it to wet the cleaning cloth, and performs floor cleaning in the same way as mopping with a general straw. While some steam can be in contact with the surface to be cleaned and can be mopped with hot liquid, the price is inexpensive, while the vacuum suction has to be performed separately.

2) Steam injection vacuum suction method

The steam injection port is installed near the vacuum inlet (mainly directly behind) to perform vacuum suction at the same time as the steam injection, so that dirt on the cleaning floor can be cleaned a little more than the simple vacuum suction method. Insufficient floor cleaning in Korean ondol floor environment. Because the cleaning cloth and the floor are in direct contact with each other, the dirt is not easily removed.

The present invention is to provide a steam mop combined vacuum cleaner that can perform a mop function and a vacuum cleaning function at the same time smoothly.

In another aspect, the present invention is to provide a steam-mop combined vacuum cleaner that can remove the dirt strongly bound to the surface to be cleaned and to perform the disinfection of the surface to be cleaned.

Another object of the present invention is to provide a vacuum mop combined vacuum cleaner for purifying and discharging air sucked with dirt.

According to the present invention, the cavity body has a connection hole and is formed with an opening groove forward; A skirt extending forwardly from the cavity body; A steam supply pipe having a steam nozzle coupled to the cavity body; A mop plate coupled to the cavity body such that the steam nozzle is exposed toward the bottom; And a vacuum suction path formed of the opening groove and the skirt of the cavity body by a negative pressure transmitted through a cylindrical handle bar connected to the connector and pivotally coupled to the connection hole of the cavity body. A vacuum cleaner and a cleaner head capable of cleaning a mop by a mop cloth attached to the mop plate are provided.

The mop plate has irregularities and / or air suction holes for fixing the mop cloth. Since the negative pressure is formed through the connection hole in the cavity body, the mop cloth or the mop can be fixed by the suction hole formed in the bottom of the mop plate. The mop cloth may also be fixed by fastening means such as clips formed on the front, rear, left and right sides of the cavity body.

The skirt is integrally fixed or slidably coupled to the body. At this time, the skirt is preferably in the form of a single plate, but may be in the form of a pipe for a constant suction pipe. It is possible to advance by spring and back by wall pressure to make the mop possible as far as possible towards the wall. The bottom of the floor is sucked through a vacuum suction path which is opened to the front and formed by the skirt and the cavity body.

In addition, the cleaner head according to the present invention;

A cleaning body including a steam generating means, a vacuum pump, a waste container, a discharge air separating means, and a power supply means for supplying power to the steam generating means and the vacuum pump;

Plumbing means for connecting the cleaner head and the cleaning body and configured the handle, steam supply pipe and the suction pipe passage; And

A steam type vacuum cleaner including a control means mounted near the handle grip and simultaneously performing the cleaning of the steam mop is provided.

The steam supply pipe is generally made separately from the suction pipe and is easy to manage. However, the steam supply pipe line and the suction pipe line may form a coaxial pipe to the connector through the handle connecting rod. At this time, the steam supply pipe connected to the steam nozzle can maintain the water supply line despite the pivoting movement of the handle using a flexible hose material.

The steam generating means includes a steam discharge valve, steam passage heater. The steam generating means is mounted on the main body to supply steam to the steam nozzle of the cleaner head along the steam supply pipe, but may simply be mounted on the upper portion of the cavity body. The steam generating means may further include a pressure sensor or a water level sensor to measure the pressure or the water level.

One or more baffles may be installed in the waste container to form a water channel. The exhaust air separating means is made by various filters. For example, it may include a solid separation filter and a gas-liquid separation filter. Solid separation filters are available in a variety of pore size filters depending on the design purpose. The gas-liquid separation filter can separate air and water using, for example, hydrophobicity. Alternatively, gas and liquid can be separated by selective membranes. Finally, the HEPA filter or the ultrafine filter is arranged to dissolve and remove water-soluble contaminants or gases by dissolving them in steam and water through the suction channel and the water channel of the waste collection container, and remove other unremoved harmful substances through the filter It emits much better air than a cleaner. It is easy to manage that the discharge air separating means is cartridgeized and coupled to the outlet side of the waste container. The waste container may preferably have a discharge port at the bottom in a removable form.

The control means is preferably mounted on the handle, particularly preferably placed near the grip of the handle so that it can be easily manipulated.

 The steam vacuum cleaner of the present invention can be used for wet cleaning of windows or carpets as well as floor cleaning. It is preferable not to use mop cloth when cleaning carpets.
