Problems solved by technology

[0003] However, if such a deodorizing method is adopted, the contact area between the deodorizing material and the dust is small, and the contact time is also very short, so there is a problem that a sufficient deodorizing effect cannot be produced.
For this reason, depending on the type of dust and the period of accumulation, the exhaust airflow of the electric vacuum cleaner may sometimes have a foul smell, which makes the user feel very uncomfortable.

Embodiment 1

[0038] figure 1 It is a cross-sectional view showing a general structure of an electric vacuum cleaner. exist figure 1 Among them, a body 1 of the electric vacuum cleaner is provided with a front roller 2 and a pair of rear wheels 3 mounted on a pivot. The front portion of the body 1 is provided with an air suction port 4 for attracting dust. In addition, although it is not shown in the figure, the suction head for attracting dust is connected with the suction port 4 through an extension tube and a hose, continuously Perform dust suction operation. In addition, in the machine body 1 , a dust collection chamber 5 and an electric blower 6 are sequentially provided in the downstream direction of the dust suction port 4 .

[0039] The specific structure is as figure 2 As shown in , the body 1 of the electric vacuum cleaner is provided with a dust collection chamber 5 and an electric fan 6 for attracting dust. The dust collection chamber 5 is provided with a dust collection ba...

Embodiment 2

[0047] Figure 4 shows the second embodiment of the present invention. Here, for the same parts as those in the above-mentioned embodiment 1, repeated description thereof will be omitted, and only different parts will be described. In Embodiment 2, the pulverization / granulation device 9 is set in a movable state, and the deodorizing material 10 becomes granular or powdered with the movement of the pulverization / granulation device 9 . exist Figure 4 Among them, 11 is a drive device such as a vibrator for driving the pulverization / granulation device 9, and this drive device is controlled by a control unit 14 arranged at an appropriate position in the body of the vacuum cleaner. When the vacuum cleaner body 1 is connected to the power socket or the operation switch of the vacuum cleaner body 1 is turned on, the control unit 14 is energized. In addition, 12 in the figure is an elastic member such as a spring, which is used to press the deodorant material 10 on the pulverizatio...

Embodiment 3

[0055] Figure 5 Example 3 of the present invention is shown in . For the parts that are the same as those in Embodiments 1 and 2 above, repeated descriptions thereof will be omitted, and only different parts will be described. In Example 3, the pulverization / granulation device 9 is vibrated manually, and 16 is a manual operation part for realizing this purpose.

[0056] In this embodiment, when deodorization is required, the user only needs to grasp the operation part 16 to make the pulverization / granulation device 9 vibrate back and forth, so that the deodorant material 10 can be made into granular or powdery, so that it can be used at any Time to deodorize.

[0057] In addition, although the vibration driving mechanism of this pulverization / granulation device 9 is not shown in detail in the figure, it can be used to make the pulverization / granulation device 9 interlock with the electric wire reel of the power cord, and when the power cord is pulled The output and winding...

Abstract

The invention aims to improve the deodorization performance of an electric dust collector. The invention comprises an electric fan (6) for collecting dust, a dust-collecting chamber (2) for capturing and collecting dust, and a deodorizing device for adding a particulate or powdery deodorant (10) into the dust-collecting chamber (2) or the upstream side thereof. The dust and the particulate or powdery deodorant (10) intermix under the attraction action of the electric fan (6). Therefore, the invention provides the electric dust collector with excellent deodorization performance. Additionally, the deodorant is mixed with dust under the attraction action of the electric fan, so that it is unnecessary to arrange a special mixer and the machine structure is simplified.

Description

technical field [0001] The present invention relates to a deodorizing method and a deodorizing device for deodorizing peculiar smells from dust, and an electric vacuum cleaner using the deodorizing method and deodorizing device. Background technique [0002] In current deodorizing methods, deodorizing devices, and electric vacuum cleaners using these deodorizing methods and deodorizing devices, the dust inhaled by the electric vacuum cleaner is captured / collected by paper bags and dust collection filters installed in the dust collection chamber, These paper bags and dust collection filters have been soaked with deodorant, and such peculiar smell is deodorized by deodorant (one example of which can refer to Japanese Patent Publication No. Hei 5-70871). [0003] However, in such a deodorizing method, the contact area between the deodorizing material and the dust is small and the contact time is very short, so there is a problem that a sufficient deodorizing effect cannot be pr...
