And the window part 31 is formed in the part which faces the dust collection chamber 21 which is the internal space formed in the cleaner main body 11 in the cover part 30 (refer FIG. 4). The window portion 31 is an opening formed in the cover portion 30 .

On the cover 30, as shown in FIG. The situation is essentially the same.

On the front side of the window cover 33, there is formed a grip portion 33a for catching fingers when lifted upward and removed. In addition, the window cover 33 is fitted into an annular holding recess 32 d provided on the outer peripheral portion of the window portion 31 .

Moreover, the holding protrusion 32a is provided in the front side, and the holding rib part 32b is provided in the rear side in the peripheral part of the dust collecting chamber 21 side of the window part 31. As shown in FIG.

The holding protrusion 32a is provided at a position separated from the window portion 31 by a set distance downward, and extends in the left-right direction (the direction perpendicular to the front-rear direction, that is, the width direction) of the cleaner body 11 . And, the tip of the holding protrusion 32a is formed in an R shape as shown in FIG. 5 .

On the other hand, a plurality of holding ribs 32b are provided at predetermined intervals in the left-right direction (width direction) of the cleaner main body 11, and as shown in FIG. . Further, a holding recessed portion 32c is formed on an upper portion of the front end of the holding rib portion 32b, that is, in the vicinity of the window portion 31 .

The photocatalyst medium 40 includes a photocatalyst filter (deodorizing member) 41 and a frame 42 for holding the photocatalyst filter 41 as shown in FIG. 2( a ).

The photocatalyst filter 41 is substantially alternately formed by overlapping photocatalyst sheets (photocatalyst members) 41a containing photocatalyst substances and bamboo charcoal sheets 41b containing bamboo charcoal substances. Here, the photocatalyst sheet 41a is bent into a wave shape, and the photocatalyst filter 41 forms a honeycomb structure (see FIG. 2( b )).

The frame body 42 has an annular holding frame (ultraviolet illuminant) 42a made of transparent resin surrounding the photocatalyst filter 41, and a plurality of mounting frames 42b connected to the lower part of the holding frame 42a. The photocatalyst filter 41 is arrange|positioned in the holding frame 42a in the form which the hole of a honeycomb structure extended in the up-down direction, and is mounted on the mounting frame 42b.

Furthermore, the holding frame 42a is formed into an annular shape from a transparent acryl member, and corrugated or the like is applied to the outer periphery. Thereby, when ultraviolet rays are irradiated inside from a part of the holding frame 42a, ultraviolet rays can be emitted from the entire holding frame 42a to radiate ultraviolet rays.

Furthermore, on the upper portion of the outer peripheral surface of the holding frame 42a, as shown in FIGS. 5 and 6 , an engaging protrusion 43 protruding outward is provided along the entire circumference. By making the engaging protrusion 43 of the holding frame 42a on the front side detachably engage on the holding protrusion 32a of the cover part 30, and making the engaging protrusion 43 of the holding frame 42a on the rear side fit in the recess 32c of the holding rib 32b The upper part is detachably engaged, so that the photosensitive medium 40 is detachably mounted on the cover part 30 .

In addition, a buffer member 44 is provided on the upper end surface of the holding frame 42a. When the photoreceptor 40 is mounted on the cover 30 by using the buffer member 44, the frame body 42 can be prevented from directly contacting the peripheral portion of the window portion 31. .

As shown in FIG. 4 , a light source (ultraviolet light emitting source) 50 that emits ultraviolet rays (ultraviolet light emitting source) 50 that is close to and in contact with the engaging protrusion 43 of the holding frame 42a is installed on the cover portion 30, and the lead wire 51 connected to the light source 50 , 52 are connected to terminals 51a, 52a. As this light source 50, an ultraviolet lamp etc. can be used.

Furthermore, the terminals 51a and 52a are attached to a resin-made terminal stand 53, and this terminal stand 53 is held by a bracket 54 attached to the front end of the cover 30 as shown in FIG. 4 .

Furthermore, on the front end upper part of the main body case 20, as shown in FIG.3(b), the terminal 51b, 52b exposed to the upper surface is attached. Furthermore, when the cover 30 is closed as shown in FIG. 3( a ), the ends 51 a and 52 a of the cover 30 can come into contact with the ends 51 b and 52 b of the main body case 20 as shown in FIG. 3( b ).

[effect]

Next, the operation of the electric vacuum cleaner having such a configuration will be described.

When the switch S1 or S2 provided on the hand-held operation tube 13 is turned on, the control circuit 55 will drive the electric blower 22 . When the electric blower 22 is driven, a suction negative pressure is generated, and through the dust collection chamber 21, the dust collection hose 12, the hand-held operation tube 13, the extension pipe 14 acts on the suction chamber (not shown) of the suction port body 15 to inhale the negative pressure. pressure. Utilize this suction negative pressure, the dust and air on the surface to be cleaned are sucked from the suction opening of the suction chamber provided on the bottom surface of the suction port body 15, and flowed to The dust collection chamber 21 of the cleaner main body 11 sucks.

The dust sucked into the dust collection chamber 21 is collected by the dust collection bag F provided in the dust collection chamber 21, and after the air is sucked by the electric blower 22 in the motor chamber, it is discharged from the exhaust hole not shown in the main body 11 of the vacuum cleaner. and was expelled.

On the other hand, bacteria and the like flow into the dust collecting chamber 21 together with dust and air, and odor components such as ammonia and acetaldehyde are emitted from the dust collecting bag F and the like. This odor component is decomposed and deodorized by the photocatalyst filter (deodorizer) 41 of the photocatalyst 40 provided in the cover body 30 located in the upper side of the dust collection chamber 21. As shown in FIG. Moreover, bacteria themselves are also sterilized and decomposed by the photocatalyst filter (deodorizing member) 41 .

Moreover, the structure which decomposes an odor component etc. by this photocatalyst filter (deodorizing member) 41 is as follows.

The photocatalyst substance which the photocatalyst sheet 41a of the photocatalyst filter (deodorizing member) 41 has is titanium dioxide ( _TiO2 ), for example.

When this titanium dioxide is irradiated with light (ultraviolet rays), electrons are ejected from the surface to form positively charged holes called holes. The holes have a strong oxidative power, and will take electrons from the surrounding organic matter to form an electrically stable state.

In this way, the organic matter deprived of electrons by the oxidation-reduction action of titanium dioxide is decomposed, and finally forms carbon dioxide, water, etc., and emits them in the atmosphere. Moreover, the bamboo charcoal sheet 41b has adsorption force and can absorb odor components.

Here, since the photocatalyst filter (deodorizing member) 41 is arranged substantially along the window portion 31 formed on the cover portion 30, it can be fully irradiated by the light (ultraviolet rays) incident by the window portion 31, and high deodorization can be obtained. Stink effect.

In addition, since the photocatalyst filter 41 is arranged on the frame body 42 in the form that the holes of its honeycomb structure extend in the up-down direction, so the odor components can pass between the photocatalyst sheet 41a and the bamboo charcoal sheet 41b, and stimulate deodorization.

And, the air flowing into the dust collecting chamber 21 hardly passes through the photocatalyst filter (deodorizing member) 41 provided along the window portion 31 of the cover 30, and the dust sucked into the dust collecting chamber 21 hardly adheres to it. On the photocatalyst filter (deodorizing member) 41.

And, because this photocatalyst filter (deodorizing member) 41 is installed on the lid portion 30 detachably, so even if there is dust attached to the photocatalyst filter (deodorizing member) 41, it can be easily removed. The photocatalyst medium 40 provided with the photocatalyst filter (deodorizing member) 41 is cleaned or replaced.

In addition, since the photocatalyst filter (deodorizing member) 41 is formed in a honeycomb shape, the external light taken in from the window portion 31 reaches the dust bag F through the gap of the honeycomb shape, and the ultraviolet rays in the external light are subjected to photocatalyst treatment. The dust bag F of the dust bag F acts, and uses the part of the dust bag F treated by the photocatalyst to decompose the odor components.

On the other hand, the control circuit 55 turns on the light source 50 when the switch 13b for lighting the illuminants is turned ON. The ultraviolet light emitted from the light source 50 enters the holding frame 42 a and is emitted from the entire holding frame 42 a to emit ultraviolet light.

A part of this ultraviolet ray is irradiated on the photocatalyst filter (deodorizing member) 41, and the odor component is decomposed by the photocatalyst filter (deodorizing member) 41. FIG.

Moreover, another part of the ultraviolet rays irradiates the dust bag F treated with photocatalyst, so that the odor components in the dust bag F are decomposed.

In addition, since a part of the ultraviolet rays passes through the window portion 31 and is radiated upward to the outside, it is seen from the outside that the window portion 31 emits faint purple light. Thereby, the user can know that the deodorization process is being performed in the dust collecting chamber 21 . Especially at the time of use such as at night, it can be known that the deodorizing treatment is being performed.

Moreover, since the photocatalytic medium 40 can always be cleaned in advance, the decomposition will not be hindered by the dust adhering to the photocatalytic medium 40, and sufficient deodorizing effect can be maintained for a long time.

Moreover, since the photocatalyst medium 40 can be easily cleaned or replaced, even if the photocatalyst filter 41 is exposed in the dust collection chamber 21, the fall of the deodorizing effect can be prevented. And a high deodorizing effect can be acquired by exposing this photocatalyst filter 41.

And in the daytime, external light enters through the window portion 31, and ultraviolet rays contained in the external light are irradiated to the photocatalyst filter (deodorizing member) 41 and the dust bag F to decompose the odor components. On the other hand, at night when there is little external light sucked in from the window portion 31, by emitting light from the light source 50 to emit ultraviolet rays, the ultraviolet rays can be introduced into the holding frame 42a, and the entire holding frame 42a can radiate ultraviolet rays, and use The photocatalyst filter (deodorizing member) 41 and the dust bag F etc. decompose the odor components. By using the ultraviolet rays contained in the external light and the ultraviolet rays emitted by the holding frame 42a respectively during the day and night in this way, wasteful consumption of energy can be avoided, and the odor in the dust collecting chamber 21 can be effectively decomposed. .

(Modification 1)

In the above-described embodiment, the outer peripheral surface of the holding frame 42a is corrugated to emit ultraviolet rays from the entire holding frame 42a, but the present invention is not necessarily limited to this.

As shown in FIG. 8 , a lens portion 56 may be provided at the lower end of the holding frame 42 a, and ultraviolet rays may be irradiated downward from the lens portion 56 . In this case, the ultraviolet ray can irradiate the dust bag F through the lens portion 56 at the lower end of the holding frame, and decomposes the odor component in the dust bag.

(Modification 2)

In the above-described embodiments, an example in which the holding frame 42a is used as an ultraviolet illuminant was shown, but it is not necessarily limited thereto.

For example, a configuration as shown in FIGS. 9 and 10 may also be employed. In this FIG. 9 , the window portion 31 is formed in an ellipse as shown in FIG. 10 , and on the portion of the window cover 33 facing the window portion 31 , a cover portion protruding portion 33 a with an arc-shaped cross-section curved and protruding upward is formed. . Moreover, the front part of the cover part protrusion part 33a is sunk downward as shown in FIG. 9, FIG. 10, and the recessed part 33b is formed.

On the cover portion 30, a holding concave portion 32d extending circularly along the window portion 31 as shown in FIG. 9 is provided. The holding recess 32d is formed between inner and outer double annular flanges 32d1 and 32d2 protruding upward along the window portion 31 . The inner annular flange 32d1 has an annular raised portion d1a, and an annular inner protrusion d1b protruding inward relative to the annular raised portion d1a.

Also, the amount of protrusion from the annular rising portion d1a along the edge portion 30b of the window portion 31 of the cover portion 30 is formed very small, and the amount of protrusion of the annular inner protrusion d1b from the annular rising portion d1a is set to be small. big.

Between the annular inner protruding portion d1b and the edge portion 30b of the cover portion 30 along the window portion 31, an annular ultraviolet light emitter 57 made of transparent resin elastically engaged with the annular rising portion d1a is held. As shown in FIGS. 9 to 11 , the ultraviolet light emitter 57 has a ring-shaped light emitter (light emitter) 57a formed in advance, and a protrusion 57b for ultraviolet light incident protrudingly provided at the rear of the ring light emitter 57a.

A light source (ultraviolet light source) 58 that emits ultraviolet rays is provided at the rear end of the protruding portion 57b. This light source 58 is also controlled by the control circuit 55 shown in FIG. 7 in the same manner as in the above-mentioned embodiment.

Then, by making the light source 58 emit light and making the ultraviolet rays from the light source 58 enter the protruding part 57b, the incident ultraviolet rays are made incident on the annular light emitting part 57a, and the ultraviolet rays are emitted from the whole. The ultraviolet rays emitted from the annular light emitting portion 57a irradiate the entire obliquely upper periphery of the photocatalyst filter 41 as a deodorizing member, and the photocatalyst filter 41 decomposes odor.

In addition, at this time, ultraviolet rays can be recognized from the cover protrusion 33 a, so that the operating state of the ultraviolet light emitter 57 can be confirmed.

(Modification 3)

In addition, as shown in FIG. 12, the part of the above-mentioned cover part protrusion part 33a may be made into an ultraviolet light emitter. In this case, the leg part 33c may be provided on the cover protruding part 33a side, and the light source 33d which emits an ultraviolet-ray may be made to face the end surface of this leg part 33c. In this case, ultraviolet rays can be irradiated to the photocatalyst filter 41 from the whole cover part protrusion part 33a from the periphery.

(Modification 4)

In the above-described embodiments, the ultraviolet illuminant 57 is shown as an example of forming a ring from the beginning, but it does not necessarily have to be a ring.

That is, it is also possible to form a linear illuminant made of transparent resin in a circularly curved manner between the annular inner protruding portion d1b and the edge portion 30b of the cover portion 30 along the window portion 31 to form a light emitting body as shown in FIG. 13 . Ultraviolet illuminants59. In this case, the 1st light source 60 and the 2nd light source 61 can be made to face each edge part 59a, 59b of the ultraviolet ray emitter 59, respectively. In addition, the ultraviolet illuminant 59 uses a flexible light guide having a structure in which a cylindrical fluororesin tube is filled with an elastomer material.

In this case, if the first light source 60 and the second light source 61 are used as light sources for emitting ultraviolet rays, the amount of ultraviolet rays incident on the ultraviolet light emitter 59 can be increased. Also, in this case, it is possible to prevent the light quantity of the central portion of the ultraviolet illuminant 59 from decreasing.

Moreover, if the first light source 60 is used as a light source emitting ultraviolet rays, the second light source 61 is used as a light source emitting visible light such as blue light, and the first and second light sources 60, 61 are made to emit light at the same time, then the ultraviolet light emitter While 59 emits ultraviolet rays from the whole, it also emits blue visible light from the whole of the ultraviolet illuminant 59 .

This blue visible light can be recognized from the window portion 31 , so when the blue visible light is seen through the window portion 31 , it is possible to visually confirm that ultraviolet rays are emitted from the ultraviolet light emitter 59 .

In addition, although the 2nd light source 61 is a light source which emits blue visible light, it is not necessarily limited to this. That is, the second light source 61 may be a light source that emits visible light other than blue.
