Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sanitary cleaning device that is combined with a toilet bowl and has a means for cleaning a part of a human body to be cleaned, a means for drying the part to be cleaned after cleaning, and a deodorizing means.

Generally, this type of sanitary cleaning device is combined with a Western-style toilet bowl 1 as shown in FIG. The so-called toilet bowl 1 is equipped with a means for spraying cleaning water from a nozzle 4 for cleaning, a means for drying the area to be cleaned by blowing hot air after cleaning, and a means for sucking in the odor inside the toilet bowl 1 and deodorizing it through a deodorizing agent. It is configured as a multi-function device. To explain more specifically, the sanitary washing device includes a pump 6 that sucks water from a low tank 5 installed in a toilet and pumps it to the nozzle 4;
and a hot water tank 7 provided between the nozzle 4 and the nozzle 4 and equipped with a heater for heating the cleaning water, a motor 8 for generating hot air for drying the part of the human body to be cleaned, a fan,
It consists of a drying device 9 consisting of a heater (not shown), a deodorizing device 11 consisting of a fan and motor (both not shown) for sucking odor from the toilet bowl 1, a deodorizing agent tank 10, and other operating parts.

By the way, although it is useful because it has many functions, it is necessary to install separate motors and fans for the drying means and deodorizing means, which increases the volume of the entire device and increases manufacturing costs. This is undesirable from the viewpoints of power consumption and power consumption.

On the other hand, it is conceivable to simply have one fan device and have it serve as both the drying means and the deodorizing means, but it is not practical to install a heater and a deodorizing agent with relatively high ventilation resistance in one ventilation path. There is a problem. In other words, when hot air is sent out for drying, the deodorizer in the ventilation path creates a large resistance, making it impossible to blow out the hot air strongly, reducing air blowing efficiency, and requiring the use of a motor with greater capacity. Furthermore, since the ventilation in the ventilation passage is poor, there is a risk that the heater in the ventilation passage may overheat and burn out the constituent members, so a safety device must be added.

The present invention has been made in consideration of such conventional problems, in which a single fan device is used both as a drying means and a deodorizing means, and in which the fan unit is effectively provided with two parts.
The object of the present invention is to provide a sanitary cleaning device in which two wind cylinders are selectively connected.

To achieve this object, the present invention provides a sanitary cleaning device equipped with a cleaning device, a deodorizing device, and a drying device, including a first wind barrel that communicates with one fan portion and is provided with a deodorizing member inside the fan portion; The second wind cylinder, which communicates with the fan section and has a heater inside, is configured to selectively communicate with the fan section by switching a damper having a devised damper plate.

A hot water tank 21 provided on the downstream side and having a heater (not shown), and a nozzle 22 connected to the hot water tank 21 and disposed inside the toilet bowl 14 to eject cleaning water, further controlling the temperature of the cleaning water, A control unit 23 for adjusting the toilet seat temperature, etc. is provided.

In addition, numeral 24 in the figure is a starting switch that is activated by the weight of the user when he or she sits on the toilet seat 15, and is used to energize a fan device, which will be described later.

On the other side of the upper part of the base member 18 are a wind barrel component 25, a motor 26 and a fan 27 shown in FIG. It includes an adjustment section 30 and the like. In addition, 31 in the figure is a timer, and after the user leaves the toilet seat 15 after use and the start switch 24 is turned off, the motor 26 is turned off.
This is to maintain the drive for a certain period of time.

The relationship between the wind barrel component 25, the motor 26, and the fan 27 is configured as shown in FIG.
That is, the wind body component 25 has the fan chamber 3 at one end.
2, and also has a first wind barrel 33 and a second wind barrel 34. The first and second wind cylinders 3
Openings 35 and 36 at one end of 3 and 34 open into the fan chamber 32 in a coplanar relationship, and openings 37 and 38 at the other end are located at the edge of the center portion of the base member 18, It faces into the toilet bowl 1. Further, the wind cylinders 33, 3 of the fan chamber 32
The face plate (top plate in this embodiment) perpendicular to the openings 35, 36 of No. 4 has the openings 35, 36
Openings 39 and 40 are formed on the extension of 6 and have substantially the same shape as the respective openings 35 and 36 (see FIG. 4). A motor 2 is installed in the fan chamber 32.
6 and a sirotsko type fan 27 directly connected to this motor. In addition, the wind barrel 33, 3
A damper is provided at a portion where the surfaces of the openings 35 and 36 of the fan chamber 32 and the surfaces of the openings 39 and 40 of the fan chamber 32 are perpendicular to each other.
41 shafts 42 are rotatably provided. This damper 41 is attached to the shaft 42 as shown in FIG.
A damper plate 43 and a second damper plate 44 are arranged side by side in the axial direction. The first damper plate 43
The relationship between the damper plate 44 and the second damper plate 44 is such that they protrude on planes that are perpendicular to each other. And the first damper plate 4
3 has a shape that projects on one side of the shaft 42, and the second damper plate 44 consists of a pair of plate pieces 44a and 44b that project on both sides of the shaft 42. These first
The plate pieces 44a, 44b of the damper plate 43 and the second damper plate 44 are shaped to individually close the openings 35, 36 of the wind barrels 33, 34 and the openings 39, 40 of the fan chamber 32, respectively. .
Further, one plate piece 4 of the second damper plate 44
An actuating piece 45 for actuating a switch to be described later is protruded from the tip of 4b.

The damper 41 is connected to the openings 39, 40 of the fan chamber 32 and the wind barrel 3, as shown in FIGS. 7 and 8.
A shaft 42 is placed on the joining line of the openings 35 and 36 of 3 and 34.
It is pivoted along the Therefore, the first damper plate 43 is in a relationship of opening and closing the opening 35 of the first wind barrel 33 and the first opening 39 of the fan chamber 32, and the first plate piece 44a of the second damper plate 44 opens and closes the opening 36 of the second wind barrel 34, and the second plate piece 44b opens and closes the second opening 40 of the fan chamber 32. Furthermore, the second plate piece 44b
When the second opening 40 of the fan chamber 32 is closed, the operating piece 45 protruding from the end thereof presses the drying heater switch 46 provided at the edge of the opening 40 to turn it on. have a relationship.

One end of the shaft 42 of the damper 41 is connected to connecting members 47, 48, 4 as shown in FIGS.
9 to an operating knob 50, and by rotating the operating knob 50, the damper 41 can be switched. One end portion of the shaft 42 is formed as a square shaft portion 51 as shown in FIG. 9, and is held between two elastic plates 53 and 54 whose both ends are held by a holding member 52. Therefore, the shaft 42 makes an articulated rotation of 90 degrees, and
Keep this rotating position stable. More specifically, as shown in FIG. 9b, the square shaft portion 51 has a cross section that is not a regular quadrilateral but is a quadrilateral deformed like a rhombus with acute angles and obtuse angles. Therefore, when pressed between two parallel elastic plates 53 and 54,
As shown by the arrow in the figure, it is receiving a force that tries to rotate it in one direction (counterclockwise in the figure). Therefore, the operating piece 45 of the plate piece 44b strongly pushes the switch 46, and the first and second damper plates 43, 44 are pressed against the edge of the opening to be closed.

A deodorizer loading port 5 is provided in a part of the first wind barrel 33.
5, and a deodorizer cartridge 56 filled with a deodorizer such as activated carbon is inserted from the deodorizer loading port 55. A heater 57 is installed inside the second wind barrel 34 to generate warm air. Therefore, the first wind cylinder 33 is used as a deodorizing wind cylinder, and the second wind cylinder 34 is configured as a drying wind cylinder. Note that these wind barrel structures are integrally molded from synthetic resin such as polypropylene.

Next, the operation of the sanitary cleaning device having the above configuration will be explained. When the user sits on the toilet seat 15, the start switch 24 is turned on due to weight, and the motor 26 is energized to rotate the fan 27. By setting the drying and deodorizing operation unit 28 to the deodorizing side, deodorizing operation is performed as will be described in detail later. When the user finishes his errands, he operates the pump 19 as appropriate and sprays warmed washing water from the nozzle 22 to wash the part of the user to be cleaned. When the cleaning is finished, the drying and deodorizing operation section 28 is switched, and warm air is blown out from the opening 38 to dry the area to be cleaned. After that, drying and deodorizing operation section 2
Return 8 to the deodorizing side. When the user leaves the toilet seat 15, the start switch 24 is turned off, but after the deodorizing operation is performed for a certain period of time due to the action of the timer 31, the power is turned off.

As mentioned earlier, this invention uses one motor 2
6 and a fan 27 are commonly used for deodorizing and drying, and the feature is the switching means of the wind cylinder. This device has a fan chamber 32 at one end of a wind barrel component 25, a first wind barrel 33 equipped with a deodorizing member such as a deodorizing cartridge, and an opening 35 at one end of a second wind barrel 34 equipped with a heater 57. , 36 are arranged on one surface with respect to the fan chamber 32, and openings 39, 40 are provided respectively corresponding to the openings 35, 36 provided in the fan chamber 32, and each of these openings is connected to a damper. 41, the first wind cylinder 33 and the second wind cylinder 34 are selectively opened to the fan chamber 32, and deodorizing and drying operations are selected.

That is, based on the shape of the damper 41 shown in FIG. 9, when the operation knob 50 is placed in the switching position as shown in FIG.
3 is opened, and the corresponding first opening 39 of the fan chamber 32 is closed. on the other hand,
Among the second damper plates 44 of the damper 41, the plate piece 44a closes the opening 36 of the second wind barrel 34,
Furthermore, the corresponding opening 40 of the fan chamber 32 is not closed by the plate piece 44b. The operating piece 45 of the plate piece 44b is the switch 4.
6, the heater 57 in the second wind barrel 34 is not energized and does not generate heat. Therefore, in the state shown in FIG. 7, only the first wind cylinder 33 is related to the fan 27, and the rotation of the fan 27 sucks the odor inside the toilet bowl 14 through the opening 37. When passing through the deodorizer, the air is deodorized and released from the opening 39 of the fan chamber 32. And the second wind cylinder 34 is not functioning at all. In other words, only the deodorizing function is available.

Next, as shown in FIG. 8, when the operating knob 50 is switched, the damper 41 is rotated approximately 90 degrees. In this state, the first damper plate 43 closes the opening 35 of the first wind barrel 33, and the second damper plate 4
The fourth plate piece 44a opens the opening 36 of the second wind body 34, and the plate piece 44b closes the opening 40 of the fan chamber 32. The operating piece 45 then presses the switch 46 to turn it on, energizing the heater 57 in the second wind barrel 34 and causing the heater 57 to generate heat. Therefore, only the second wind cylinder 34 is associated with the fan 27, and the first wind cylinder 33 does not function at all. As the fan 27 rotates, outside air is sucked in through the opening 39 of the fan chamber 32, and is forced into the second wind cylinder 33, warmed by the heater 57, and then transferred to the opening 3.
8 and sprays it onto the part of the human body to be cleaned to dry it after cleaning.

The heater 57 in the second wind barrel 34 is energized only when the operating knob 50 is switched to the dry mode system, that is, it generates heat only when the second wind barrel 34 is ventilated. This eliminates the risk of burnout due to abnormal heating caused by heat generation in the second wind barrel 34 when there is no ventilation in the deodorizing mode, making it extremely safe.

Further, in the drying mode, the first wind cylinder 33
Since it is blocked, deodorizing cartridge 5
6 is not related to the ventilation of the second wind barrel 34, that is, there is no problem of a decrease in ventilation efficiency due to the deodorizing cartridge 56.

In switching the damper 41, since there is a square shaft part 51 at the end of the shaft 42 of the damper 41, and this part is sandwiched between two elastic plates 53 and 54, the rotation of the damper 41 can be switched almost immediately. It is performed at a 90° angle.

Furthermore, as shown in FIG. 9b, since the square shaft portion 51 is deformed into a diamond shape and is pressed by the elastic plates 53 and 54, the shaft 42 rotates slightly in one direction while being fixed. energized damper plate 4
3, 44 and the switch 46 is turned on by the operating piece 45.

Note that the first and second wind barrels do not necessarily need to be integrally molded, and may be arranged in parallel. Further, the fan is not limited to a Sirotskov fan, and the heater in the wind barrel may be a honeycomb-shaped heater made of a positive temperature characteristic resistance element, instead of a nichrome wire heater. Further, the cleaning function member and the toilet seat heating configuration are not limited to those shown in the drawings.

As explained above in the embodiments, the present invention uses one fan for both deodorizing and drying, and can switch between deodorizing mode and heating mode by controlling the opening and closing of four openings by operating one damper.
It is easy to operate and contributes to miniaturization and cost reduction of the device.
