Abstract

<P>PROBLEM TO BE SOLVED: To provide a cleaner with an air jetting function so as to lessen fatigue by reducing the resistance of an object and a nozzle when cleaning is performed by means of the cleaner and so as to make the cleaning of a gap efficient, and to provide the cleaner also having a hot-air jetting function so as to dry and sterilize a cleaning region. <P>SOLUTION: Characteristically, an air exhaust nozzle (3) is provided near the suction opening (2) of a suction nozzle (1) of the cleaner, and a jet of air or hot air is emitted from the exhaust nozzle (3). <P>COPYRIGHT: (C)2004,JPO

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner with an air outlet, which is provided with an air outlet at the same time as a suction nozzle of a cleaner.

[0002]

2. Description of the Related Art In a conventional vacuum cleaner, a dust suction nozzle has only a suction port.

[0003]

However, this has the following drawbacks. (B) For example, when cleaning a blanket or a soft carpet, an excessive negative pressure tends to be generated between the nozzle and the object. Therefore, the target object is easily attached to the nozzle, the resistance between the target object and the nozzle is increased, the movement of the nozzle is difficult, and cleaning is difficult. In addition, the object is often completely adsorbed, and it is necessary to separate the object with your hand or turn off the suction switch every time, especially when people who are not physically fit do the cleaning. It was accompanied. Also,
In such a state where the resistance to the object is large, only the negative pressure between the nozzle and the object progresses, the air flow around the suction port is small and it is not possible to sufficiently suck the dust, and in terms of time and power consumption. Even the cleaning efficiency was poor. (B) Flooring It is difficult to clean dust that has accumulated in narrow or narrow areas such as gaps in the floor of floors, corners of walls and floors, door movement grooves, etc. The garbage could not be removed sufficiently. After all it was inefficient in terms of time and power consumption. (C) Although it was possible to aspirate dust, it was not possible to remove germs such as germs latent in the object. (D) For example, when spilling foods such as beverages and soups onto carpets and cleaning the soiled parts, some dust is removed, but there is no function to dry the wet parts. The present invention has been made to eliminate the above drawbacks.

[0004]

(A) An air outlet (3) is provided in the vicinity of a suction port (2) of a cleaner nozzle (1). (B) A mechanism (4) for preheating the air ejected in (A) is provided. The present invention is a vacuum cleaner with a blow-out port, which is composed of (A) or (A) and (B).

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. (A) An air ejection port (3) directed toward an object is provided near the suction port (2) of the cleaner nozzle (1), and air is ejected from the air ejection port (3) to be sucked from the suction port. The air ejected from the air ejection port (3) may be a form in which the air sucked from the suction port (2) to the cleaner body is circulated and all or part of the air is ejected (FIG. 1). It is also possible that the air taken in from the outside is ejected from the cleaner body (Fig. 2).
Only one air outlet (3) is required (Figs. 4 and 6)
There may be a plurality (FIGS. 5 and 7). In the above structure, when using this, it may have a function to adjust the amount of air to be ejected by manual operation, and the ejection amount can be automatically adjusted according to the suction force and the degree of negative pressure. It may have a control function. The air blown out from the air blowout port (3) sweeps out fine dust such as a gap in the cleaning target portion, and the dust is sucked into the cleaner body through the suction port (2) of the nozzle. (B) Due to the heat generated by the heater (4) embedded in the main body of the cleaner or the suction hose, or the motor itself in the cleaner, the air to be ejected is preheated before being ejected. (Figure 3) When using this in this structure,
It may have a function of heating the jetted air or not, or adjusting the heating temperature.

[0006]

Since the air ejected from the air ejection port (3) is sucked from the suction port (2) via the target site,
It is possible to constantly create a flow of air while preventing an excessive negative pressure between the suction nozzle (1) and the object. Therefore, it is possible to sufficiently reduce the movement resistance between the nozzle and the object when moving the nozzle, and to sufficiently have the function of sucking dust. Further, this air jetting function makes it possible to sweep out dust collected in a narrow portion or a narrow portion and suck the dust. As a result, it is possible to perform cleaning more efficiently in a shorter time than conventional ones, there is a power saving effect, an effect of reducing fatigue during cleaning, and an effect of preventing damage to an object by reducing movement resistance between the nozzle and the object. Also, by having a mechanism for ejecting heated air together, it becomes possible to sterilize and dry the target site.
