BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust bag of an electric vacuum cleaner configured to collect dust in a room or the like into a cleaner body by a suction force of a motor. In order to be able to suck dust such as cigarette butts that are ignited by fire, a dust bag is installed in the dust collecting part of the vacuum cleaner with a sprinkler installed in the cleaner body so that the sprinkler can function sufficiently. By doing so, the present invention relates to a dust collecting bag for an electric vacuum cleaner capable of improving safety.

[0002]

2. Description of the Related Art In recent years, with the advent of various household electric appliances accompanying the development of industry, the convenience of daily life has increased, but inaccurate use of these products may lead to accidents.

[0003] For example, when a cigarette carrying a fire is sucked into an electric vacuum cleaner, the filter in the electric vacuum cleaner is ignited, and there is a risk of causing a vacuum cleaner fire and eventually burnout in the vicinity of the vacuum cleaner. .

For this reason, various vacuum cleaners have been developed which are equipped with a water spraying device for extinguishing fire in the vacuum cleaner body in order to be able to suck dust that is ignited by fire. It is put to practical use in various pachinko parlors.

[0005] Conventionally, in the electric vacuum cleaner (electric vacuum cleaner capable of sucking combustible dust) equipped with a sprinkler for extinguishing a fire, the dust bag (filter) in the dust collecting portion is burnt out,
And, in order to prevent the promotion of fire due to the dust bag, the dust bag made of a combustible member such as paper or cloth is not used,
It was configured as follows.

That is, a stainless steel net is provided above the dust collecting portion or behind the dust collecting portion (in the direction of the suction motor) so that a volatile member (such as a cigarette butts carrying fire) cannot pass through the volatile material. The member is retained and stored in a dust collecting part made of a fire-resistant material such as stainless steel to prevent the expansion of fire and to be extinguished by the sprinkler in the dust collecting part. By disposing a filter made of paper or cloth at a position behind the net and in front of the suction motor, passage of fine dust is prevented, and the dust is prevented from being discharged to the outside.

[0007]

However, there are various problems as described below in the case where the dust is accumulated and stored in the dust collecting portion as in the above-mentioned conventional technique.

In other words, if the dust is directly stored in the dust collecting section as in the above-mentioned conventional method, when the dust is discarded, the dust storing section having the dust collecting section (having a size approximately half of the cleaner main body) is provided. There has been the trouble of having to lift it up to the upper part of the incinerator and invert it.

Further, in order to solve the above-mentioned problems, if a disposable paper dust bag is installed in the dust collecting portion, the fire is promoted as described above, and it goes against the recent trend of resource protection. It will be a negative factor in both disaster prevention and corporate attitude.

On the other hand, when the dust bag is made of a flame-retardant member, the temperature sensor of the water sprinkler cannot detect the fire in the dust collecting part quickly, and the temperature sensor senses the fire to eject the dust from the jet nozzle. It is difficult to put the fire extinguishing water into practical use because it is not sufficiently radiated to the dust that burns in the dust collecting section, and there is a risk that the inside of the cleaner body will be burnt out.

Further, if the two-stage construction of the stainless net for restraining the passage of the flammable member and the filter for restraining the passage of the fine dust as in the above-mentioned conventional case, the structure of the cleaner body becomes complicated. There was a point.

The present invention has been made in view of the above circumstances, and relates to an electric vacuum cleaner equipped with a sprinkler device in a cleaner body so as to be capable of sucking fired dust such as cigarette butts. A dust bag for an electric vacuum cleaner is provided in which the safety is improved by mounting a dust bag that allows the water sprinkler to function sufficiently in the dust collecting section.

[0013]

DISCLOSURE OF THE INVENTION The present invention relates to an electric vacuum cleaner equipped with a sprinkler device in which fire extinguishing water is jetted from a jet nozzle when a temperature sensor detects a high temperature state in a dust collecting portion. The above object is achieved by providing a dust bag for an electric vacuum cleaner, characterized in that the vicinity of the sprinkler device of the fire-resistant dust bag attached to the above is constituted by a combustible member.

Further, the present invention is installed in an electric vacuum cleaner equipped with a sprinkler device in which fire extinguishing water is jetted from a jet nozzle when a temperature sensor detects a high temperature state in a dust collecting portion. By providing a dust-collecting bag for a vacuum cleaner, characterized in that a portion to which the main portion of the water-spraying device can be fitted is provided at a location near the water-spraying device in the fire-resistant dust-collecting bag. It achieves the task.

[0015]

The dust collecting bag for the electric vacuum cleaner according to the present invention not only functions to store the sucked dust inside, but also functions as a filter for letting out only the air to the outside. It works as a deterrent inside, and also works so that a quick and sufficient spray of fire extinguishing water by a water sprinkler can be created in the dust bag.

In the dust collecting bag for an electric vacuum cleaner according to claim 1, when the dust contained in the dust collecting bag is burned by sucking a cigarette butts or the like which is ignited by fire, the flammable member is burned by the flame, As a result, the fire extinguishing water is surely sprayed from the location into the dust bag by the spray nozzle of the sprinkler.

Further, before the burnable member is burned down, the temperature sensor detects an abnormality (the dust collecting section senses about 50 ° C.) or the cleaner notices an abnormality (smoke, etc.), and the fire extinguishing water is ejected from the injection nozzle. When sprayed, the fire-extinguishing water damages the flammable member and sprays in the dust bag.

On the other hand, in the dust collecting bag for an electric vacuum cleaner according to claim 2, when the suction of the outside air is started by the driving of the suction motor, the dust collecting bag becomes enormous, so that the dust collecting bag is attached. Since the part comes to be fitted into the spray nozzle and the temperature sensor of the sprinkler, and further the spray nozzle and the temperature sensor project into the dust collecting bag, the detection ability of the temperature sensor (in the dust collecting bag) Immediate detection of fire) is improved, and the fire extinguishing water in the dust bag is reliably injected from the injection nozzle.

Since the tip of the injection nozzle and the tip of the temperature sensor are tapered, fitting and insertion of the adhered portion can be performed easily and reliably.

Further, since the filter main body other than the flammable member and the adhered portion is made of a fire resistant member such as alumina fiber or high silica fiber, the dust bag itself does not burn, and thus the flame is extended. Does not spread around.
