Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device. The present invention includes a deodorization device for use by hooking the flush toilet bowl waist hanging type. Further, it includes a device configuration that can be set on either the left side or the right side of the toilet body.

[0002]

2. Description of the Related Art As a deodorizing device to be installed in a seat-type flush toilet, for example, as disclosed in Japanese Utility Model Publication No. 1-111814 and Japanese Patent Laid-Open No. 1-268929, a rim portion around a ball of a toilet body is used. There is a method that uses the rising edge to hook. Including these examples, the conventional deodorizing device has a configuration in which the part to be hung on the rim is an odor suction path from the ball part, and a fan for suction, a deodorant or an ozonizer is stored in the part hanging outside the toilet body. It is common.

Further, as in the latter publication, an optical sensor is provided in the main body of the deodorizing device for detecting the presence of a person,
In some cases, the fan and the ozonizer are automatically activated when a person uses the toilet bowl, and automatically stopped after the person leaves the toilet bowl.

[0004]

However, in the conventional structure, since the intake port that faces the ball portion across the rim portion and the main body portion of the deodorizing device located outside the toilet bowl are integrally formed, Intake part cannot be easily disassembled. For this reason, in order to clean the tip of the intake port, which is in a posture facing the ball portion and is most likely to be exposed to dirt and dirty water, it is necessary to remove the entire apparatus from the toilet body, which is a time-consuming task. Also, even when cleaning, it is enough to wipe the whole, especially because the intake port is integrally molded, so there is a limit not only to the inside but also to the depth into which the rag can be inserted, so it is sufficient It is impossible to have good cleanliness.

Further, when the deodorizing device is set on the stool-type toilet, since a person sits or stands up from the front side of the toilet body, there is no choice but to use the left or right side surface. For this reason, for example, when the specification is such that the deodorizing device is set on the left side of the toilet body when viewed from the front, the body and the intake port are integrated, so if you set the deodorizing device on the right side of the toilet body depending on the situation at the site, Front and back posture is reversed. Therefore, although the left specification is used, the back side faces the front, which is not preferable in terms of appearance.

Further, when the deodorizing device is automatically operated according to the use of a person by using the sensor, if a sensor is incorporated in the main body of the device, in order to detect the presence of the person, the front of the main body is detected. The sensor will be located and will detect the person's leg. In this case, the left specification cannot be used for the right specification unless the sensor is provided on the front surface and the back surface of the main body. Therefore, it is necessary to prepare two types of products, that is, the left and right specifications, as a product, and it is likely that cost obstacles and production management will be complicated.

One problem to be solved in the present invention is
The purpose is to make it easy to clean, including the part that is likely to be exposed to dirty water, and to use it by setting it on both the left and right sides of the toilet body with one specification. Furthermore, it is also included in the subject of this invention to provide the deodorizing apparatus which can solve the various subjects mentioned in the Example of this specification.

The present invention comprises a housing having a suction fan and a deodorizing function built therein, and a hanger connected to the upper end of the housing and capable of being hooked on the rim of the toilet body.
A deodorizing device in which the hanger has a hollow structure, a base end of which is connected to a flow path to the fan and a tip of which is opened so as to face a ball portion of the toilet body, wherein the hanger is vertically attached to the housing. It is characterized in that it has a shape that extends laterally from the upper surface of the housing as a posture that intersects with the axis of the direction, and that the hanger is attached so as to be rotatable around a contact point with the housing.

The hanger may be removably connected to the housing.

Further, the hanger may be composed of at least two members that enclose the internal flow passage, and these two members can be disassembled from each other.

[0011]

[Function] Since the hanger having a shape extending laterally from the upper surface of the housing can be swung with respect to the housing,
When the front direction of the housing is fixed, the hanger can be in a posture in which it projects to the right and a posture in which it projects to the left. Therefore, by rotating the hanger on both the left side and the right side of the toilet body, the housing can be attached to the toilet body with the front face always facing the front.

By turning the hanger, the rim can be fixed between the hanger and the housing while adjusting the positional relationship between the hanger and the housing according to the rim shape of the toilet.

Further, by removing the hanger from the housing, it is possible to wash the tip of the hanger that is easily exposed to dirty water and dirt, and further disassemble the hanger itself to clean the internal flow passage.

Further, three ribs 2e are projected on a portion extending toward the tip side of the base 2a, and two ribs 2e on the outer side are formed.
The shape with the width between is extended downward from the tip side. The cover 2b is removable from the base 2a, and its tip extends to a position slightly protruding from the portion where the base 2a bends downward.

The base 2a and the cover 2b form a suction flow path to the communication port 1a inside the hanger 2, and the fan 4 operates to suck air from the tip of the hanger 2 to guide the guide 3 and the duct. The gas is exhausted from the discharge port 1d via 5.

FIG. 5 is a perspective view when the deodorizing device is set on the toilet body 20.

A flush water tank 21 is provided on the back of the toilet body 20.
And a toilet seat 22 and a toilet lid 23 are provided on the upper surface. In the deodorizing device, the hanger 2 at the upper end of the housing 1 is placed in the posture shown in FIG.
It is set by hanging this hanger 2 on a.

When the hanger 2 is hung on the rim 20a, if the distance between the bent portion under the base 2a and the housing 1 is set to be substantially equal to the width of the rim 20a, the hanger 2 is simply fitted to the housing 1. Can be fixed as a posture along the side surface of the toilet body 20. Further, when the width of the rim 20a is short, if the hanger 2 is turned to the front side or the rear side, the edge portion of the base 2a can abut against the ball-side surface of the rim 20a, and stable fixing is possible. Is. On the contrary, it is also possible to rotate the housing 1 and abut it against the side surface of the toilet body to fix it.

In addition to fixing the housing 1 as described above, a spacer may be inserted between the bent portion of the base 2a and the inner wall of the rim 20a. Further, if the base 2a is made of an elastic material such as synthetic resin so as to have a distance between the base 2a and the housing 1 that fits tightly in the width of the rim 20a, the base 2a can be fixed by elastic deformation of the base 2a when sandwiching the rim 20a.

In the above structure, as shown in FIG. 5, the housing 1 of the deodorizing device is set on the toilet body 20 with the sensor unit 8 facing forward, so that when a person sits on the toilet seat 22, The leg part can be detected. Then, this detection signal is input to the controller 9, and the driver 6a operates the ozonizer 6 and simultaneously drives the fan 4.

By the operation of the fan 4, air is sucked from the tip of the hanger 2 which is open to the ball portion side of the toilet body 20, and flows in the order of the guide 3, the fan 4 and the duct 5. Then, the air deodorized by the ozonizer 6 and the catalyst 7 and deodorized is discharged from the discharge port 1d.

FIG. 6 shows an example in which the deodorizing device is set on the right side of the toilet body 20 when viewed from the front.

In this case, the housing 1 shown in FIG.
The hanger 2 cannot be attached to the
The hanger 2 is turned 180 ° about the flange 1b of the communication port 1a as the center of rotation. As a result, the hanger 2 is arranged to extend to the left with respect to the housing 1 and can be hung on the right rim 20a of the toilet body 20 in the same manner as in FIG. The orientation of the housing 1 itself is the same as in the case of the left side arrangement, and the sensor unit 8 is set in a posture in which it faces the front, and the seating of a person can be detected.

Since the shape of the housing 1 is formed substantially symmetrically in the vertical direction and the surface facing the toilet body 20 is substantially flat, the housing 1 can be attached to either the left or right side of the toilet body 20 without any discomfort.

As described above, by making the hanger 2 having two functions, one for fixing and the other for intake passage, which is hung on the rim 20a of the toilet body 20 rotatable with respect to the housing 1 having a built-in functional portion, the toilet The deodorizing device can be set on either the left side or the right side of the main body 20.

Since the hanger 2 can be attached to and detached from the housing 1, it is possible to remove only the hanger 2 and wash it with water. Since the hanger 2 itself can also be disassembled into the base 2a and the cover 2b, they can be washed separately. Therefore, even the hanger 2 that easily faces the ball portion of the toilet body 20 and is easily covered with dirty water and dirt can be sufficiently washed with water and can always be kept clean.

FIG. 7 is a sectional view showing the peripheral portion of the ozonizer of the deodorizing apparatus according to the embodiment of the present invention. The deodorizing device according to this embodiment includes a flow path 32 for air containing a malodorous component and a discharge element 43 for an ozonizer 41 installed in the air flow path 32; Element 4
A flow path partition plate 37 that defines the ozonizer front flow path 53 including the three discharge surfaces 44 is provided.

In FIG. 7, the air containing the malodorous component flows downward from the housing communication port 1a shown in the figure, and the guide 31
The air is passed through the inner air flow path 32, and is sucked into a fan (not shown) from a circular fan suction port 35 opened in the lower part of the guide 31.

An ozonizer 41 is fitted on the left side plate 34 of the guide 31. The ozonizer 41 includes a discharge element 43 having a discharge surface 44. A corona discharge area is formed on the discharge surface 44 of the discharge element 43, and a part of oxygen in the air passing through the corona discharge area is changed to ozone. Due to the strong oxidizing power of this ozone,
The odorous components in the air are decomposed. A catalyst for decomposing the malodorous component and excess ozone is provided on the outlet side of the fan.

A flow path partition plate 37 is erected on the front surface of the discharge surface 44 of the discharge element 43 so as to face the same surface 44. Therefore, the ozonizer front flow path 53 including the discharge surface 44 is defined. On the side opposite to the discharge surface 44 of the flow path partition plate 37, a flow path of air flowing without directly contacting the discharge surface 44,
That is, the main flow path 32 is defined. In this figure, the main flow path 32 is larger than the ozonizer front flow path 53, and most of the air is in the main flow path 3.
2, but the invention is not limited to such an embodiment.

The role of the flow path partition plate 37 is to turbulently or smoothly adjust the air flow on the surface of the discharge surface 44 depending on its shape, and the air flow inlet constituted by the flow path partition plate 37 and the guide 32. By changing the area of 51, the generation amount and concentration distribution of ozone generated on the discharge surface 44 of the discharge element 43 are controlled to an optimum state for decomposition of the malodorous component.

In the case of the flow path partition plate 37 shown in FIG. 7, the above-mentioned ozonizer front flow path 53 has the narrowed inlet 5
1 and spread toward the downstream side. As one effect of doing so, compared with the case where the flow path partition plate 37 is not provided, the air contacting the discharge surface can be reduced, and the ozone generation amount can be reduced as much as possible.
Naturally, the amount of ozone generated can be controlled by adjusting the size and electrical characteristics of the ozonizer 41. However, there are many cases where it is necessary to reduce the cost by using an existing product for the ozonizer 41, and such a flow path partition plate 37 allows the use of the existing product for the ozonizer, which makes it possible to inexpensively control the ozone generation amount. The technical significance of being able to do is high.

FIG. 8 is a cross-sectional view showing a modified example of the flow path partition plate for defining the front flow path of the ozonizer. The flow path partition plate 37 ′ shown in FIG. 8 has an entrance side curved portion 58,
The airflow rectified by the same portion 58 is directed to the discharge surface 44. Therefore, the air flow on the surface of the discharge surface 44 can be disturbed.

FIG. 9 is a sectional view showing another modification of the flow path partition plate for defining the front flow path of the ozonizer. The flow path partition plate 37 ″ in this figure has an entrance-side straight line portion 59, and an ozonizer front surface flow path 53 that is in contact with the entry side linear part 59 gradually expands from the inflow port 51 toward the flow path in front of the discharge surface 44. Therefore, there is no portion where the air flow is disturbed, and it is possible to form a rectified air flow in which the flow velocity is gradually reduced in front of the ozonizer front flow passage 53 ″. On the contrary, by widening the inlet and narrowing the outlet, the air flow is stagnated in the front flow path 53 and the supply of new oxygen is suppressed, so that it is possible to control the ozone generation amount. It is also possible to make the entrance side wide and control so as to increase the ozone generation amount. Further, as another role of the flow path partition plate 51, when the hanger is removed and cleaning or the like is performed, it is possible to prevent a finger from entering through the communication port 1a and touching the discharge surface of the ozonizer to receive an electric shock.

From another point of view, the deodorizing device according to the embodiment of FIG. 7 has a housing 1, a communication port 1a opened in the housing 1, and an air flow path 32 connected to the communication port 1a. And a guide 31 that defines the air flow path 32
And an ozonizer 41 for generating ozone in the air containing a malodorous component flowing through; a pipe-shaped apron 1x is attached to the communication port 1a, and the guide 31 includes the apron 1x and a labyrinth-shaped pipe. It is characterized in that a guard 33 that engages with is attached.

The air (including other gases, which is the same in the present specification) as a target of the deodorizing apparatus contains water (including liquid content, mist and the like, which is the same in the present specification). There are also cases. Such air enters the air passage 32 in the housing 1 through the communication port 1a of the housing 1. On the other hand, since electrical components for driving the ozonizer 41 and the like are arranged in the housing 1 outside the guide 31 that defines the air flow path 32, outside the guide 31,
It is necessary to prevent air from flowing in. Due to the labyrinth effect of the apron 1x and the guard 33, the inflow of air from the communication port 1 into the housing 1 outside the guide 31 is blocked.

From another point of view, the deodorizing device according to the embodiment of FIG. 7 has a housing 1, a communication port 1a opened in the housing 1, and an air flow path 32 connected to the communication port 1a. And a guide 31 that defines the air flow path 32
An ozonizer 41 for generating ozone in the air containing a malodorous component flowing through the ozonizer 41; the ozonizer 41 covers a discharge element 43 having a discharge surface 44 and a non-discharge surface of the discharge surface 44 of the discharge element 43. Back plate 45
, And the back plate 45 is the guide 3
It is characterized in that it is set on one side plate 34.

With this structure, although the temperature becomes high due to the discharge (the temperature of the ceramic forming the discharge surface of the ozonizer becomes high), the heat can be prevented from being directly transmitted to the side plate 34 of the guide 31. Furthermore, if the back plate is of a type that fits into the guide, the ozonizer 41 can be easily set on the guide 31. Further, the airflow (water) can be shut off at the fitting portions of the back plate 45 and the guide side plate 34. It should be noted that the retaining after the fitting is done by setting the housing (cover).

As shown in FIG. 7, since the ozonizer 41 and the sensor unit 8 are arranged on the opposite sides of the air flow path 32, the discharge surface 44 of the ozonizer 41 discharges. It is possible to reduce the influence of electromagnetic noise generated when the sensor is present on the sensor.

FIG. 10 is a cross-sectional view showing a connecting portion between the housing body and the hanger in the deodorizing device which is essentially the same as the deodorizing device for the toilet shown in FIGS. This deodorizing device for a toilet comprises a deodorizing device main body and a hanger 2 that is connected to the deodorizing device main body and has an air flow path inside, and the hanger 2 is attached to the rim 20 of the toilet in a hook shape. The deodorizing device of the above; a communication port 1a to which the air flow path of the hanger 2 is connected is formed in the upper part of the housing 1 of the deodorizing device body, and a U-shaped groove is formed around the communication port 1a. And a restraining piece 1c are provided, and the hanger flange 61 is inserted into the U-shaped groove and rotatably engages with the hanger 2 on the hanger 2.
The sheet packing 69 is provided between the lower surface of the hanger flange 61 and the upper surface of the housing 1 so as to be sandwiched between the inner end surface 63 of the hanger flange 61 and the inner surface of the U-shaped groove. Is equipped with an O-ring 67.

The hanger flange 61 is basically in the form of a perforated disc, and the periphery of the inner end surface 63 is fitted into the U-shaped inner surface (groove) formed by the housing flange 1b and the restraining piece 1c. Has been. The housing flange 1b also has a ring shape, and the hanger flange 61 is rotatable around the housing flange 1b. The hanger flange 61 is partially cut out at several places in the circumferential direction, and if the notch and the restraint piece 1c are aligned with each other, the hanger flange 61 can be pulled out upward (Fig. The same as the structure shown in 2).

The sheet packing 69 sandwiched between the lower surface of the hanger flange 61 and the upper surface of the housing 1 fills the gaps on both surfaces. The sheet packing 69 is made of foamed plastic, for example, and has a thickness of 1 mm (preferably 0.5 mm or more), which is rich in flexibility and elasticity. Therefore, even when the hanger 2 is bent (the force of twisting is exerted by the weight of the main body of the deodorizing device), there is no gap between the hanger flange 61 and the upper surface of the housing 1. Therefore, it is possible to prevent water and dirt from entering the housing 1. As the sheet packing, it is also preferable that one surface of the foamed plastic has a smooth resin surface such as PP (69a in FIG. 10B). By doing so, even if the foam is originally slippery, it can follow the rotation smoothly without being twisted by the rotation of the hanger.

The O-ring 67 is the seat packing 69.
Similarly to the above, it not only prevents the invasion of water and the like from the outside of the housing 1 but also provides an appropriate sliding friction resistance between the hanger flange 61 and the housing flange 1b. By the function of the O-ring 67, the hanger 2 can be set to the main body housing 1 at an arbitrary angle (a part other than the part where the hanger comes out).

FIG. 11 is a sectional view showing the toilet-side tip of the hanger when the deodorizing device for a toilet according to one embodiment of the present invention is attached to the toilet. This deodorizing device for a toilet comprises a deodorizing device main body and a hanger 2 that is connected to the deodorizing device main body and has an air flow path inside, and the hanger 2 is attached to the rim 20a of the toilet in a hook shape. Deodorizing device; air passage 2 of the hanger 2
The tip of the w on the toilet side has an air intake port (2z) that opens toward the inside of the toilet, and the position of this intake port is above the highest water level surface 71 at the time of an abnormal toilet, which is the upper surface of the rim 20a. It is characterized by

In an abnormal case such as when the toilet bowl is clogged, the highest possible water level surface 71 in the toilet bowl is the upper surface of the rim 20a of the toilet bowl. When the water rises to this point,
If a large amount of water flows into the suction port 2z of the hanger 2, the ozonizer, the catalyst, and the electrical components in the deodorizing device body will break down. In order to prevent such a situation, the position of the suction port 2z is above the highest water level surface 71.

Such measures for preventing water from flowing into the deodorizing device are also taken in the deodorizing device shown in FIG.
That is, the deodorizing device body is composed of a deodorizing device body and a hanger 2 which is connected to the deodorizing device body and has an air flow path inside. The hanger 2 is a deodorizing device for a toilet that is attached to the rim 20a of the toilet in a hook shape. The tip of the air passage 2w of the hanger 2 on the toilet side has an air intake port (2z) that opens toward the inside of the toilet, and the side port 2 is on the side of this intake port.
When t is opened and water is accumulated in the toilet up to the maximum water level surface 71 (upper surface of the rim 20a) when the toilet is abnormal,
Air is sucked into the air flow path 2w from the side port 2t.

In the deodorizing apparatus of FIG. 1, if there is no side opening 2t at the tip of the hanger 2, when water reaches the highest water level surface 71, a considerable negative pressure is generated in the air passage 2w of the hanger. , Water in the toilet bowl is sucked toward the body. However, such a situation does not occur because the air enters the hanger air passage 2w from the side opening 2t.

From a different point of view, the toilet deodorizing device of FIG. 11 is composed of a deodorizing device main body and a hanger 2 which is connected to the deodorizing device main body and has an air passage therein, and the hanger 2 is a toilet bowl. Deodorizing device for a toilet attached to the rim 20a of the hook in a hook shape;
The tip of the toilet side has an air intake port (2z) that opens toward the inside of the toilet, and the hook portion 2x that hangs down from the end of the hanger 2 is provided with a reinforcing rib 2e.

Since the hanger 2 of this deodorizing device must be passed between the toilet rim 20a and the toilet seat 22 (FIG. 5), its height is limited. Therefore, the wall thickness of the portion forming the hanger cannot be sufficiently obtained. Under such conditions, it is necessary to increase the rigidity of the hanger 2 and secure a wide air flow passage 2w. Therefore, in order to increase the strength of the same portion of the hanger and prevent the hanger from being bent when it is pressed from above, a rib 2e extending in the air flow direction is provided on the base 2a of the hanger.

The rib 2e also extends continuously to the hook portion 2x at the tip of the hanger 2 (the portion that falls into the toilet 20 and hooks on the rim 20a). With this rib 2e,
The rigidity of the hook portion 2x is increased. In particular,
In the deodorizing device of this embodiment, the suction port 2 of the hanger 2
z is open on the rim 20a and the cover 2
Due to the structure in which b does not extend downward (the reason is described above), the cover 2
The rigidity contribution of b does not reach the hook portion 2x. Therefore, the rib 2e of the hook portion 2x plays a particularly important role in avoiding the inclination of the main body of the deodorizing device.

From a different point of view, the toilet deodorizing device of FIG. 11 comprises a deodorizing device main body and a hanger 2 which is connected to the deodorizing device main body and has an air passage therein, and the hanger 2 is a toilet bowl. Deodorizing device for a toilet attached to the rim 20a of the hook in a hook shape;
The tip of the toilet on the toilet side has an air inlet 2z that opens toward the inside of the toilet, and has a wedge-shaped cross section between the back surface of the hook 2x that hangs down at the end of the hanger 2 and the rim 20a of the toilet. It is characterized by having a pad 75.

As shown in FIG. 11, in some rims 20a of the toilet bowl, the inner wall surface thereof is oblique (spreading upward). When the deodorizing device for a toilet shown in FIG. 11 is attached to such a toilet, the hook is deformed by the oblique shape of the rim, so that the deodorizing device main body is inclined. But,
Since there is a wedge-shaped pad, the above-mentioned wedge-shaped pad 75 is useful for improving the hooking of the hook portion 2x and avoiding the inclination of the main body of the deodorizing device.

FIG. 12 is a view showing the internal structure of the main body housing of the deodorizing apparatus according to the embodiment of the present invention. The guide 3, the fan 4, the catalyst 7, the controller 9 and the like are removed from the state of FIG. Further, the position of the sensor unit 8 is at the lower right in the deodorizing device of FIG. 2, whereas it is at the upper right of the deodorizing device of FIG.

The deodorizing device shown in FIG. 12 comprises a deodorizing device main body and a hanger 2 which is connected to the deodorizing device main body and has an air flow path inside. The hanger 2 is a rim 20 of a toilet bowl.
A deodorizing device for a toilet attached to a in the form of a hook; the housing 1 of the deodorizing device main body has a multi-part mating structure, and the outer skin 82 of the housing 1 along the mating line.
A waterproof member 83 is inserted inside the.

In a housing in which a large number of parts are arranged, it is often a combined structure such as a two-split structure. On the other hand, in the case of a hook-type toilet deodorizing device, small amount of water or water is often splashed, and it is necessary to take measures against it. As a waterproof structure of the joint of the housing,
Generally, there is a structure in which a packing is sandwiched and a joint is tightened with a bolt or the like. However, in the domestic deodorizing device for a toilet, which is the object of the present invention, such a heavy structure cannot be adopted in terms of cost and design.

Housing 1 of the deodorizing device of the embodiment shown in FIG.
By the way, it has a structure in which two parts of a plastic injection molded product are hooked and assembled by engaging hooks (not shown). In such a housing, it is difficult to ensure the waterproofness of the joint due to the molding error of the parts and the insufficient tightening force between the parts. In such a case, simply place a thin sheet (plastic, etc.) as a waterproof member along the back of the seam, and the water entering from the seam will be reflected by this thin sheet to the inside of the housing. It can prevent intrusion and can easily and effectively produce waterproof fruits. As a waterproof member, a rib protruding from the main body may be provided at the rear portion (inside) of the seam (see FIG. 23).

Deodorizing device housing 1 of the embodiment shown in FIG.
Furthermore, inside the housing 1 along the mating line, ribs 81, 85, 9 parallel to the housing skin 82 are provided.
1, 95 are provided, and the outer skin 82 and ribs 81, 85 are provided.
The waterproof sheet 8 is provided between the outer skin 92 and the ribs 91 and 95.
3, 93 are interposed.

By doing so, the waterproof sheet 8
It is possible to easily insert 3, 93 into the correct position. Furthermore, if the height of the internal ribs 81, 85, 91, 95 is made higher than the seam of the housing 1, the labyrinth effect further enhances the waterproof property. 12
12B is a view showing a right lower section BB cross section of the housing of FIG. 12A. As shown in the figure, a waterproof sheet 83 is interposed between the rib 85 and the outer skin 82 so as to cover the back side of the mating portion (which has an overlap structure) of the outer skin 82.

In the housing of the deodorizing device shown in FIG. 12, the bottom surface 8 of the housing 1, which corresponds to the portion where the water adhering between the waterproof sheet 83 and the outer cover 82 falls and accumulates.
7, a drain hole 89 is opened. For this reason, the water that has entered the housing 1 is discharged to the outside of the housing 1 without entering the electrical equipment or the like. It should be noted that the water that has entered the left-side waterproof sheet 93 in FIG. 12 falls down through the sheet 93 and finally falls down from the left end of the air discharge port 1d.

The deodorizing device shown in FIG. 12 further has an deodorizing ozonizer (not shown), and the high-voltage electrical equipment section 101 including the high-frequency power source section 105 for the ozonizer serves as the pod 10.
In FIG. 9, it is resin-sealed.

The voltage of the high frequency power supply section 105 of the ozonizer is generally 4.0 to 6.0 KV. The electrical components for this ozonizer are integrated in the high-voltage component 101. Furthermore, the wiring inside the same section 101 is connected to the pod case 10
It is sealed with resin (epoxy, urethane, silicon resin, etc.) poured into the inside of the container 3. By this resin sealing, even when a large amount of water enters the deodorization device housing 1, high-voltage leakage due to corrosion, short circuit of wiring, or the like does not occur.

The pod case 103 may be a box separate from the housing 1 or may be formed as an integral rib. It is preferable to make them integrated, because both assembly and parts costs will be lower.
It is also preferable that a heat dissipation plate (aluminum plate or the like) is integrally embedded in the pod 109 so that heat generated from the wiring and parts inside the pod is released. At that time, since the heat sink is fixed by the resin inside the pod, the vibration of the heat sink is suppressed, and it is possible to prevent the elements and wirings attached to the heat sink from being adversely affected by the vibration of the heat sink (FIG. 17). reference).

The deodorizing device of FIG. 12 further has a sensor unit 8 for detecting the proximity of a human body, and this sensor unit 8 except for the back surface 8z on the inner side of the housing 1
It has a waterproof structure with no openings. FIG. 18 is a diagram showing the internal structure of the sensor unit. A box-shaped sensor window covers the sensor, the sensor circuit element, the operation display LED, and the like. The back side (lower surface in the figure) of the sensor window is covered with a sensor circuit board.

The sensor unit 8 detects the user's body (feet, etc.) and starts / stops the deodorizing device's ozonizer or fan (a delay timer may be provided). The type of this sensor may be an optical type, an ultrasonic type, or the like. As a waterproof structure of the sensor unit 8, the sensor unit 8 may be further provided with a water stop projection 8y and a rib 81 (projecting from the housing 1 side) so as to form a labyrinth.

The sensor unit 8 of the deodorizing device of FIG.
Is attached toward the front of the toilet bowl, and the sensor unit 8 is provided with a display portion 8x that indicates that the sensor unit 8 is detecting or operating.
It sticks out from the surface.

Mounting state of the deodorizing device of FIG. 12 (FIGS. 5 and 6)
Therefore, the user's face is generally above the deodorizing device. Therefore, when attaching the display unit 8x indicating that the sensor is being detected or the device is operating,
It is necessary to make it easy for the user to see from above. However, if the display portion 8x is provided on the upper part of the housing 1, the display portion 8x may be hidden by the body or clothes of the user. Therefore, the indicator lamp 8x is made to project outward from the housing 1 (right side skin 82) and the surface of the unit so that it can be easily seen from above. The sensor unit and the display unit may be separate bodies.

FIG. 15 is a diagram showing a catalyst casing of a deodorizing device according to an embodiment of the present invention. (A) is a front view,
(B) is a plan view. FIG. 16 is a view showing a casing corner portion in a state where the catalyst is incorporated in the catalyst casing of FIG.

The deodorizing device shown in FIG. 15 is a deodorizing type of a type in which ozone is mixed into an air stream containing a malodorous component and the air stream is passed through a honeycomb type catalyst 7 to decompose the malodorous component and / or excess ozone. The device is characterized in that a baffle plate 135 for disturbing the air flow is provided in the center of the inlet side of the catalyst 7.

The catalyst casing 98 of FIG. 15 has an upper surface,
It looks like a box with the front and front of the figure missing. A honeycomb type catalyst 7 is contained in the casing 98, and air is allowed to flow from the back to the front in the figure (A) and from the top to the bottom in the figure (B). The honeycomb cells of this catalyst 7 are made of SiO ₂ -based ceramics, and the surface is decomposed with O ₃ containing MnO _{2 as a} main component.
A deodorizing catalyst is carried.

The back wall 131 of the catalyst casing 98 is
It is about 15 mm (S in FIG. 15B) from the entrance side of the catalyst 7. The rear wall 131 has an upper opening 133 and a lower opening 13.
7 and 7 are opened, and between the openings 133 and 137,
It is a baffle 135, which is a wall surface that does not open. The fan 4 is provided upstream of the catalyst casing 98.
The discharge port (FIG. 2) is connected. The cross section of the discharge port of the fan is shown in FIG.
This corresponds to a figure in which the baffle plate 135 and the lower opening 137 are integrated.

The role of the baffle plate 135 is to disturb (scatter) the air flow flowing through the catalyst 7. Baffle 13
In a state without 5 (a state in which there are no obstacles or guides between the fan discharge port and the catalyst 7), air selectively flows in the central portion of the honeycomb catalyst 7, and the catalytic action in the peripheral portion of the honeycomb cannot be fully utilized. understood. In particular, as shown in FIG. 22, when the blower outlet from the fan and the center line of the catalyst are misaligned, the problem is remarkable. Note that in FIG. 22, a negative pressure is generated on the back surface of the baffle plate 135, and the lower air component is bent upward and comes into contact with the catalyst 7 uniformly. Therefore, a baffle plate 135 is attached so that air can easily flow to the peripheral portion of the catalyst. The baffle 133 has
Appropriate slopes, curves, holes, ribs, etc. may be attached to provide a structure for guiding the air flow to the periphery of the catalyst.

In the deodorizing apparatus shown in FIGS. 15 and 16, further, the catalyst 7 has a rectangular cross section, and a protective band 143 made of a flexible material is provided on the outer, upper, lower and side surfaces of the catalyst 7.
And the catalyst is housed in a plastic casing 98, and air flows to the corner of the catalyst casing 98 into which the corner of the protective band 143 of the catalyst fits. It is characterized in that a corner seal rib 127 is provided to prevent it.

In many cases, a honeycomb catalyst made of a brittle material such as ceramics has a protective band made of foamed plastic or the like wound on the outer surface (excluding air holes). This is to prevent the catalyst from breaking due to the force (bolt tightening force, etc.) when the catalyst is attached to the deodorizing device and the impact force when the catalyst is dropped during assembly. When the honeycomb catalyst has a rectangular shape (rectangular shape or the like), as shown in FIG. 16, the catalyst 7 itself, the protective band 143, and the radius 14 at the essence portion (corner portion) are provided.
It is generally attached with 4. Therefore, if the corner portion of the catalyst casing is made into a sharp corner (right angle, etc.), there is a gap (space 147) at the corner portion of the casing.
Will be created. If air containing a malodorous component or ozone passes through this space 147, the undecomposed malodorous component or ozone may come out of the deodorizing device.

In order to solve the above problem, in the catalyst casing 98 of the deodorizing apparatus shown in FIGS. 15 and 16, a corner seal rib 127 is provided at the corner of the catalyst casing, and this rib is fitted into the protective band 143 of the catalyst 7. , The air flow at the corner is not generated. In addition, as for the corner seal rib 127, if the hypotenuse of the triangle has a shape with a concave radius, the sealing property is further improved. Needless to say, in that case, the size of the rib can be increased.
