Problems solved by technology

[0003] However, in the existing method of installing a deodorizing filter in the exhaust passage, since the suction volume of the electric vacuum cleaner is large, the contact time between the deodorizing filter and the exhaust gas flow containing peculiar smell is very short, and there is a problem of deodorization. Low odor efficiency and low odor reduction effect

Embodiment 1

[0032] First pass Figure 1~4 The electric vacuum cleaner in the first embodiment of the present invention will be described.

[0033] figure 1 It is the overall oblique view of the electric vacuum cleaner.

[0034] Inside the vacuum cleaner body 1, there is a dust collecting part (not shown in the figure) for catching / collecting dust at the front, and an electric fan (not shown in the figure) at the rear and an electric wire for rewinding the electric wire 2 Take-up device (not shown in the figure). Such as figure 1 As shown in the figure, the foremost part of the vacuum cleaner body 1 is provided with a suction port 3 communicating with the dust collecting part, and the connecting pipe 5 of the hose 4 is installed on this suction port 3 in a detachable manner. 6 is a freely rotatable running wheel installed on the two sides of the rear of the vacuum cleaner body 1, and 7 is a front cover that can open and close the dust collecting part. 8 is a handle to be grasped when carryin...

Embodiment 2

[0052] Next, the electric vacuum cleaner in the second embodiment of the present invention will be described with reference to FIGS. 5 and 6. Among them, for the same constituent parts as those in the first embodiment, only the same symbols are marked here, and the repeated description is omitted here.

[0053] Fig. 5 is an oblique view of the connecting part between the front end tube and the extension pipe of the electric vacuum cleaner in the second embodiment of the present invention, and Fig. 6 is a cross-sectional view of the extension pipe in the electric vacuum cleaner.

[0054] As shown in FIG. 5, a light emitting element mounting chamber 40 is provided on the lower surface of the front end tube 11, and the light emitting element mounting chamber 40 is provided to protrude downward. As in the first embodiment, a light-emitting element, a light-sensing element and a red light-emitting diode 23 are provided in the front end tube 11 to detect and display the dust passing con...

Embodiment 3

[0068] Figure 7 Is an oblique view of the coupling pipe in the electric vacuum cleaner of the third embodiment of the present invention, Figure 8 This is a cross-sectional view of the deodorizing material storage unit in the connecting pipe. In addition, the same parts as in the previous embodiment are marked with the same symbols, and repeated descriptions thereof are omitted.

[0069] In this embodiment, the deodorizing material storage unit 24 is provided on the connecting pipe 50 of the hose 4.

[0070] Such as Figure 7 , Figure 8 As shown in the figure, the connecting pipe cover 51 is fixed on the upper surface of the connecting pipe 50 by screws. The buckle 52 is used to connect the connecting pipe 50 to the suction port 3 in a detachable manner, and the buckle 52 is clamped between the connecting pipe 50 and the connecting pipe cover 51. On the side of the connecting pipe 50 close to the hose 4, a deodorizing material storage unit 24 is provided with a substantially do...

Abstract

The present invention provides a vacuum cleaner which has a simple structure and which is excellent in deodorization efficiency. The vacuum cleaner is provided with: a dust collection part for collecting dust; an electric blower; a cleaner body having the dust collection part and the electric blower built therein; a suction tool communicating with the electric blower for sucking dust; a deodorization material housing part 24 having an opening part 26 communicating with the dust collection part and arranged on the upstream side from the dust collection part; an opening and closing means for opening and closing the opening part 26; and a granular deodorization material 30 housed in the deodorization material housing part 24. By supplying the deodorization material 30 from the opening part 26 to a suction path communicating with the dust collection part, retention of smell in the dust collection part is reduced to markedly reduce exhaust smell which will be generated when using the cleaner next time.

Description

Technical field [0001] The invention relates to an electric vacuum cleaner, and more specifically, to an electric vacuum cleaner capable of reducing exhaust odor. Background technique [0002] In order to deodorize the exhaust of electric vacuum cleaners, it has been proposed to install a deodorizing filter in the exhaust duct. In recent years, a vacuum cleaner that uses the acidification of a photocatalyst to deodorize has emerged (for an example, refer to Japanese Patent No. 3,238,055). [0003] However, in the existing method of installing a deodorizing filter in the exhaust duct, since the suction volume of the electric vacuum cleaner is large, the contact time between the deodorizing filter and the exhaust airflow containing peculiar smell is very short, and there is a The problem of low odor efficiency and small odor reduction effect. Summary of the invention [0004] The present invention aims to solve the above-mentioned problems, and its object is to provide an electric...
