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.
A means for spraying cleaning water onto the user's area to be cleaned from a nozzle 4, a means for drying the area by applying a greenhouse to the area to be cleaned after cleaning, and a means for sucking in the deodorized inside of the toilet bowl 1 and deodorizing it through a deodorizing agent. The device is configured as a so-called multi-function device. More specifically, the sanitary washing device includes a pump 6 that sucks water from a low tank 5 installed in the toilet and pumps it to the nozzle 4, and a pump 6 that is installed between the pump 6 and the nozzle 4 to heat the washing water. A hot water tank 7 equipped with a heater, a drying device 9 consisting of a motor 8, a fan, and a heater (not shown) that generate hot air to dry the parts of the human body to be cleaned, and a fan that sucks in odors from the toilet bowl 1. The deodorizing device 11 includes a motor (none of which is shown) and a deodorizing agent tank 10, and other operating units 12 and 13.

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 purposes, the deodorizing agent in the ventilation path becomes a large resistor, making it impossible to generate a strong temperature, reducing air blowing efficiency, and requiring the use of a motor with a large capacity. Moreover, 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 structural members, so a safety device must be added.

The present invention has been made in consideration of such problems, and an object of the present invention is to provide an effective means for switching between two wind cylinders in a device in which one fan device is used both as a drying means and a deodorizing means. .

In order to achieve this object, the present invention provides a sanitary cleaning device equipped with a cleaning device, a deodorizing device, and a drying device, and includes a fan section for sucking odor from the deodorizing device and blowing air from the drying device. a first wind barrel having a deodorizing member provided inside the communicating body;
A second valve that communicates with the fan portion and has a heater provided therein.
A wind cylinder is provided, and the first wind cylinder and the second wind cylinder are selectively opened to the fan section by switching dampers, wherein a substantially diamond-shaped cam is provided on the rotation axis of the damper, and the cam The rotary position is determined by pinching and pressing between two elastic plates.

According to this configuration, at the damper switching position, the rotary shaft of the damper is always urged to rotate due to the relationship between the force of the elastic plate and the cam, and the damper plate attached to the rotary shaft is directed to the opening of the wind barrel that is to be blocked. The wind barrel can be reliably closed by crimping, and in the case where the switch is operated by pushing it with a damper plate, the switch operation can be performed reliably, thereby further improving the function of the sanitary cleaning device.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 9.

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 coplanar relationship, and openings 37 and 38 at the other end are located at the edge of the central 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 as an extension of the openings 39 and 40 and have substantially the same shape as the openings 35 and 36 (see FIG. 4). A motor 26 is installed in the fan chamber 32.
A sirotsukko-type fan 27 is connected directly to this motor. In addition, the wind cylinders 33, 34
A damper 4 for wind cylinder switching is installed in the openings 35 and 36.
1 is provided. As shown in FIG. 9, this damper 41 has a first damper plate 43 attached to a rotating shaft 42.
and a second damper plate 44 are arranged in parallel in the axial direction. The first damper plate 43 and the second damper plate 44 protrude on planes that are perpendicular to each other. The first damper plate 43 is connected to the rotating shaft 42.
The second damper plate 44 has a shape that protrudes from one side, and the second damper plate 44 has a pair of plate pieces 4 that protrude from both sides of the rotating shaft 42.
4a and 44b. The plate pieces 4 of the first damper plate 43 and the second damper plate 44
4a and 44b are the openings 35 and 36 of the wind barrels 33 and 34, and the opening 3 of the fan chamber 32, respectively.
9 and 40 are individually closed. Further, one plate piece 44 of the second damper plate 44
An operating piece 45 for operating a switch to be described later is protruded from the tip of b.

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.
The rotating shaft 42 is pivotally mounted along the joining line of the openings 35 and 36 of the openings 35 and 34. 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 44
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 the switch on. We have a relationship that allows us to One end of the rotary shaft 42 of the damper 41 is connected to the connecting member 4 as shown in FIGS. 7 and 8.
The damper 41 is connected to an operating knob 50 via terminals 7, 48, and 49, and by rotating the operating knob 50, the damper 41 can be switched. As shown in FIG. 9, one end of the rotating shaft 42 has a substantially diamond-shaped cam 51 formed thereon, and two elastic plates 53, both ends of which are held by a holding member 52.
It is sandwiched between 54. Therefore, the rotating shaft 42 is
Makes a 90° articulated rotation. To explain in more detail,
The cam 51 has a rhombic cross section with an acute angle and an obtuse angle as shown in FIG. direction (counterclockwise in the drawing). Therefore, the operating piece 45 of the plate piece 44b strongly pushes the switch 46, and the first and second damper plates 4
3 and 44 press against the edge of the opening to be closed. Next, move clockwise from the state shown in Figure 9b above.
When rotated 90 degrees, when rotated and positioned,
This time, a clockwise biasing force is generated, which also stabilizes the closing of the opening by the damper plate.

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 cylinder 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 turned on.
is energized, and the fan 27 rotates. 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 user's area to be cleaned. When the cleaning is completed, 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. Thereafter, the drying and deodorizing operation unit 28 is returned 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. . The first wind barrel 33 and the second wind barrel 3 are opened and closed by rotation control.
4 is 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, and the corresponding opening 40 of the fan chamber 32 is closed by the plate piece 44b. Not closed.
Since the operating piece 45 of the plate piece 44b is located away from the switch 46, the heater 5 in the second wind barrel 34
7 is not energized, and the heater 57 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 40 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, when the operating knob 50 is switched as shown in FIG. 8, 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 plate piece 44a of the second damper plate 44 closes the opening 35 of the second wind barrel 34.
The plate piece 44b closes the opening 40 of the fan chamber 32. Then, the actuating piece 45 presses the switch 46 to turn it on, and the heater 57 in the second wind barrel 34 is turned on.
is energized to cause 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. Then, as the fan 27 rotates, outside air is sucked in through the opening 39 of the fan chamber 32, forced into the second wind cylinder 33, warmed by the heater 57, and blown out through the opening 38 to clean the human body. Spray it on the area to dry it after cleaning. Said second wind barrel 34
The inner heater 57 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 cylinder 34 is ventilated.
This means that in the deodorizing mode, the second wind cylinder 34
This prevents accidents such as burnout due to abnormal heating caused by heat generation when there is no ventilation, making it extremely safe.

Further, in the drying mode, the first wind cylinder 33
Since it is blocked, deodorizing cartridge 5
6 has nothing to do with 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.

Particularly in switching the damper 41, a part of the rotary shaft 42 of the damper 41 has a diamond-shaped cam 5.
1, and this cam 51 connects to two elastic plates 53, 5.
4, the rotation of the damper 41 is performed at an angle of approximately 90 degrees, and as shown in FIG.
3 and 54, the rotary shaft 42 is slightly biased to rotate in one direction in a fixed state, and the damper plates 43 and 44 are in the closed state, and the actuating piece 45 is in the switch 46 state. stabilize the condition. 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 the 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 in the embodiments above, the present invention is capable of stabilizing the switching state of the two wind cylinders in a device in which one fan is used for both deodorization and drying, thereby realizing an excellent sanitary cleaning device.
