Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an odor removing device for a toilet having a function of sucking off generated odor and deodorizing it.

[Conventional technology]

As an exhaust method for exhausting an unpleasant odor generated at the time of stool and an odor remaining in the toilet, it has been common practice to use a ventilation fan of the toilet. In recent years, instead of this method, an exhaust passage has been provided in the toilet body to forcibly exhaust air by a fan, and in the case of a sanitary washing device with a local washing function, a deodorizing structure is provided inside. is there.

FIG. 7 (a) is a perspective view showing an example in which the latter sanitary washing device is installed on the toilet body, and a casing 51 of the sanitary washing device is fixed to the toilet body 50.
And a toilet lid 53 are attached respectively. A nozzle device 54 for local cleaning and a supply system of cleaning water are provided inside the casing 51, and a deodorizing duct 55 for deodorizing is incorporated. The deodorizing duct 55 is provided along the bottom surface of the casing 51 to the right sleeve as viewed from the front along the bottom surface of the casing 51, and the deodorized air is discharged from an exhaust port 51a opened on the lower surface of the casing 51 as shown in FIG. Is done.

In addition, for deodorizing and exhausting by the deodorizing duct 55, a fan for sucking air containing an odor from the suction end of the deodorizing duct 55, an ozone generator for deodorizing, and an
Deodorant cassette etc. loaded with fragrance (none shown)
Is assembled at the appropriate location.

[Problems to be solved by the invention]

The unpleasant odor generated during the toilet stool is caused by the ball portion 50a of the toilet body 50.
The suction end of the deodorant duct 55 is
It is provided to face 50a. And since it is incorporated together with the nozzle device 54, it is necessary to prevent suction of cleaning water and the like from the nozzle device 54. In order to satisfy such conditions, for example, as shown in FIG.
In many cases, the suction end of 55 protrudes forward from the rim 50b at the upper end of the toilet body 50, and a suction port 55a is provided on the lower surface of the protruding portion in many cases.

However, if the water level of the washing water in the ball 50a rises for some reason and approaches the rim 50b or becomes almost the same level, the suction port 55a also approaches the water surface of the washing water and may be covered with water. There is also. For this reason, when the fan is operated, when the suction port 55a is slightly away from the water surface, the washing water is sucked in along with the air. Also, if the suction port 55a is completely immersed in the washing water,
Only water is sucked or the fan runs idle. Thus, when the suction port 55a projects downward from the rim 50b, water is easily sucked into the deodorizing duct 55.
Therefore, the built-in fan, ozone generator, or other electric devices may be exposed to water or placed in a high humidity environment, causing rust or electric leakage.

As described above, in the deodorizing duct incorporated in the sanitary washing device, there is a condition that the air is sucked from the bowl of the toilet bowl, so that there is a problem that the washing water is easily sucked and the members are quickly deteriorated.

The problem to be solved in the present invention is to prevent the water from being sucked into the deodorizing duct even when the flush water level in the toilet rises, and to protect the equipment provided for the deodorizing function. It is in.

[Means for solving the problem]

The present invention is a device for removing an unpleasant odor in a bowl portion of a toilet body from an intake port and discharging the ball portion out of the bowl portion, wherein the intake port is located above an upper end surface of the toilet body. And a second suction port for sucking off the offensive odor in the ball portion is positioned so as to face downward from an upper end surface of the toilet body.

[Operation] By positioning the suction port above the upper end surface of the toilet body, even if the washing water in the ball portion rises abnormally, the washing water is prevented from entering through the suction port, and is incorporated in the deodorizing device. The device is not bathed in water and does not affect the deodorizing function and its operation.

Further, by providing the second suction port at a position facing downward from the upper end surface of the toilet body, the suction of air from the ball portion is performed strongly.

Therefore, with the configuration including the suction port arranged on the upper side and the second suction port, a reliable deodorizing function can be obtained including an abnormal rise of the washing water in the ball portion.

[Embodiment] FIG. 1 is a perspective view showing a main part of a deodorizing duct part of the deodorizing apparatus for a toilet according to the present invention, FIG. 2 is a side view, and FIG.
(A) and (b) are a front view and a plan view, respectively, showing a part of the deodorizing duct cut away.

As described in the conventional example, the deodorizing duct is
5 and 6 show the structure inside the casing.

The casing 1 of the sanitary washing device is fixed across the upper end of the toilet body 50 as shown in the conventional example of FIG.
FIG. 6 shows the right half of the casing 1.

A nozzle device 20 is incorporated at substantially the center of the inside of the casing 1, and a hot air device 30 for blowing hot air for drying after washing is provided on the right hand side. The nozzle device 20 has a configuration in which a nozzle body 22 built in a cylinder 21 is moved by a motor 23 in the same manner as a conventional sanitary washing device, and hot water is ejected at a washing position. The hot air device 30 is provided with a blower fan 32 and a heater 33 in a housing 31 so that hot air can be blown out from a discharge port 34 at a distal end.

In addition to the equipment incorporated for cleaning and drying, the deodorizing duct 2 is used to separate the casing 1 from the nozzle device 20.
Is fixed toward the sleeve 1a on the right end. The deodorizing duct 2 is installed under the housing 31 of the warm air device 30 to be flattened, and this portion is flattened. As shown in FIG. doing. The ozone generator 3 is housed at a position deviated to the right inside the deodorizing duct 2, and a scavenging fan 4 is provided at the right end thereof in communication therewith.

The scavenging fan 4 is disposed substantially coaxially with the axis when the deodorizing duct 2 runs to the right, and its upper half is covered by a semicircular cover formed integrally with the deodorizing duct 2. An exhaust duct 5 is incorporated under the cover using the sleeve 1a at the right end of the casing 1, and an exhaust port 5a is opened at the lower end. The scavenging fan 4 is driven by a motor 4a located on the right side of the cover unit, draws air from the suction end of the deodorizing duct 2, flows air to the exhaust duct 5, and discharges it from the exhaust port 5a. A catalyst 6 for reducing ozone used for deodorization to oxygen is incorporated in the exhaust duct 5 so that ozone does not mix with air flowing off the exhaust duct 5.

As shown in FIG. 3, the deodorizing duct 2 has an inverted concave cross section with an open lower end, and is provided with a suction head 2a as a suction port at a front portion. On the left side of the suction head 2a, an auxiliary suction portion 2b formed by cutting out so as to open the front surface and the side is provided as a second suction port. When the deodorizing duct 2 is fixed to the bottom plate 1a of the casing 1, the suction head 2a opens with its lower surface as a suction opening, and the auxiliary suction section 2b opens suction openings on the front and side surfaces.
That is, as shown in FIG.
On the other hand, the suction head 2a has an assembling structure that protrudes forward from the front edge of the bottom plate 1a, so that the area indicated by the one-dot chain line in the drawing is the suction opening. And
The opening edge 2c at the upper end of the auxiliary suction part 2b has an outer shell inclined so that the left end side is the back side, and the bottom plate 1a also forms a front edge 1b which is the same outer shell as the opening edge 2c when viewed in plan. I have. Therefore, when the deodorizing duct 2 is fixed over the bottom plate 1a,
The lower surface of the suction head 2a opens, and at the same time, the auxiliary suction unit 2b
Open the front side above 1a.

In FIGS. 1 and 2, the bottom plate 1a rests on the rim 50b of the toilet body 50, and the front edge 1b of the bottom plate 1a forming the lower side of the opening of the auxiliary suction portion 2b projects forward from the rim 50b. I have. Therefore, when the deodorizing duct 2 is put on the bottom plate 1a and fixed, the suction head 2a protrudes toward the ball portion 50a as shown in FIG. It becomes a protruding arrangement.

In the above configuration, when the motor 4a is operated, the air containing the odor in the ball portion 50a disappears from the suction head 2a and the auxiliary suction portion 2b by the suction force of the scavenging fan 4, as indicated by the arrow in FIG. It is sucked into the odor duct 2. Then, the sucked air flows in the order of the deodorizing duct 2, the ozone generator 3, the scavenging fan 4, the exhaust duct 5, and the catalyst 6, and is discharged from the exhaust port 5a. Therefore, the air containing the off-flavor is deodorized by ozone, and the odor is completely removed before being exhausted.

Here, it is assumed that the water level of the cleaning water in the ball portion 50a rises to near the upper end of the rim 50b, and the lower surface of the suction head 2a approaches the water surface. At this time, if there is only the suction head 2a having the lower surface opened, the suction force of the scavenging fan 4 acts on the cleaning water and sucks it up as shown in the conventional example of FIG. In contrast, the suction head
Even if the water surface reaches just before 2a, since the auxiliary suction part 2b is largely open above the water surface, air is sucked from the auxiliary suction part 2b even when the scavenging fan 4 is operated. That is, the air that is easily sucked takes precedence over the deodorizing duct 2
, The suction force of the scavenging fan 4 is not enough to suck up the washing water from the lower surface of the suction head 2a, and the air is continuously sucked from the auxiliary suction part 2b. Further, even if the lower end of the suction head 2a is immersed in the washing water, as long as the auxiliary suction part 2b is opened, the suction of the air from the auxiliary suction part 2b is similarly advanced, and the suction of the washing water is similarly performed. Does not occur.

As described above, in addition to the suction head 2a having the lower surface opened, the auxiliary suction portion 2b opened at a higher level than the suction head 2a prevents the washing water from being sucked into the deodorizing duct 2. Therefore, devices such as the ozone generator 3 and the scavenging fan 4 placed in the deodorizing duct 2 are not exposed to water or exposed to a humid atmosphere. Accidents can be prevented. Further, since moisture does not accumulate from the deodorizing duct 2 to the exhaust duct 5, no mold is generated in the exhaust passage, and the deodorizing function does not deteriorate.

[Effect of the invention]

In the present invention, the suction port is provided above the upper end surface of the toilet body, so even if there is an abnormal rise in the washing water in the ball portion, the suction of air is performed before the infiltration of the washing water and the suction is performed. The operation is continued without deteriorating deodorization.

In addition, by providing the second suction port, it is possible to secure a normal air suction amount, and in combination with the suction port arranged on the upper side, a stable deodorizing function is always provided irrespective of an abnormal rise of washing water. Can be obtained.
