Abstract

(57) [Summary] [Purpose] To provide an electric vacuum cleaner capable of surely and easily sucking dust and mites on a carpet or tatami mat and killing mites. [Structure] At the tip of the cleaning pipe, which has a suction pipe in the center of the ejection pipe, is provided a nozzle consisting of a ejection frame for sending air from the outer circumference to the center and a suction frame for sucking dust collected in the center. An electric vacuum cleaner having a vacuum cleaner body at the rear end for absorbing dust.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an improvement of a household or commercial vacuum cleaner.

[0002]

[Prior art]

 Conventionally, in this type of electric vacuum cleaner, a suction pipe is continuously connected to the center of the upper portion of a hollow suction head as described in Japanese Utility Model Laid-Open No. 61-92351, and a discharge nozzle is continuously connected to the center side. There is something I did. As another conventional example, there is a jetting device as described in JP-A-62-109527, which introduces exhaust air to the vicinity of a brush of a nozzle and jets a portion where the brush separates carpet piles.

[0003]

[Problems to be solved by the device]

 However, in the former type, since the air outlet is located in the center of the hollow suction head, the air discharged from the air outlet leaks outside the outer circumference of the hollow suction head, resulting in dust. Scatter dust and ticks around. Also in the latter case, a jet nozzle is provided in front of the suction nozzle so as to suck air from the rear side, and similarly, jet air leaks from the outer periphery of the suction nozzle. Further, in this example, since the exhaust pipe and the intake pipe are separately configured, there is a problem that they are complicated and difficult to handle. The present invention has been made in view of the above problems, and provides an electric vacuum cleaner capable of reliably sucking dust and mites on a carpet or tatami mat and easily killing mites. With the goal.

[0004]

[Means for Solving the Problems]

 According to this invention, at the tip of a cleaning tube provided with a suction tube in the center of the ejection tube, a nozzle composed of an ejection frame for sending air from the outer circumference to the center and a suction frame for sucking dust collected in the center is provided. It is equipped with a cleaner body for absorbing dust at the rear end.

[0005]

[Action]

 With the above structure, when cleaning the carpet, for example, by moving the nozzle back and forth, dust and mites in the pile are collected in the center of the suction frame by the air ejected from the ejection frame, and the vacuum cleaner is passed through the suction pipe. It is sent to the inside of the body and kills mites etc. by heat.

【Example】

 Hereinafter, embodiments shown in the drawings will be described in more detail. Reference numeral 1 is a cleaning pipe, and a suction pipe 3 is provided at the center of the ejection pipe 2. Reference numeral 4 denotes a nozzle, which has a flat rectangular jet frame 5 for sending air blown from the jet pipe 2 from the outer periphery to the center, and air (dust and dust) sent from the jet frame 5 having the same flat square shape. And a suction frame 6 for feeding (including mite) into the suction tube 3. Reference numeral 7 denotes a cleaner body attached to the rear end of the cleaning tube 1 for sucking dust, mites and the like, and a fragrance portion 10 including a filter 8, an electric blower 9 and a lid 10b which can be operated left and right and which contains a fragrance 10a. It is composed of Next, the flow of suction and jet air of this electric vacuum cleaner will be described. First, dust, mites, etc. sucked from the suction frame 6 of the nozzle 4 pass through the suction pipe 3 and are collected in the filter 8 of the cleaner body 7. Subsequently, the air exhausted through the electric blower 9 partially passes through the fragrance agent 10a of the fragrance portion 10 and is discharged to the outside. Note that the amount of release is adjusted by the lid 10b. Then, the other exhausted air is sent to the inside of the ejection pipe 2 through the lower portion of the cleaner body 7, and the air is ejected from the outer periphery of the ejection frame 5 of the nozzle 4 toward the center. By repeating these steps and cleaning, dust and mites can be surely absorbed, and by closing the lid 10, the temperature inside the vacuum cleaner body 7 rises, and when the temperature reaches 50 to 60 ° C, the mites die. , Other bacteria and mold can also suppress the growth. In the above embodiment, the vacuum cleaner body is a horizontal type, but it is also effective for a vertical type. Further, a rotating brush may be attached to the front surface or the rear surface of the nozzle.

[0007]

[Effect of device]

 In this device, air is blown from the outer periphery in the nozzle and dust and guni collected in the center are sucked in from the center, so air (jet) does not leak from the nozzle to the outside during cleaning, and dust and mite are not leaked to the surroundings. Work can be done without scatter. In addition, it is possible to kill mites and the like, and to release the aroma to the outside air if necessary.
