Abstract

PURPOSE:To carry out deodorization and cleaning at each use of a toilet bowl for urine by carrying out the opening and closing of a deodorizing fan and a damper which are connected with the toilet bowl for urine and flushing of cleaning water according to the signal of a sensor for detecting the approach and leaving of a human body. CONSTITUTION:A deodorizing pipe 2 is installed onto a toilet bowl 1 for urine, and a damper 3 and a fan 4 are installed into the deodorizing pipe 2, and a tank 5 for supplying the cleaning water into the toilet bowl 1 for urine and a controller 6 having a sensor 7 which is installed in a cleaning water feeding pipe are installed. When a man stands on the front surface of the toilet bowl 1 for urine, the controller 6 detects the existence from the sensor 7, and opens the damper 3 and drives the fan 4 to start deodorization. After the man leaves, the damper 3 is closed by the detection signal of the sensor 7, and the fan 4 is stopped, and the cock of the cleaning device is opened for cleaning. Therefore, deodorization and cleaning can be carried out surely at each use.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a toilet that automatically flushes and deodorizes the toilet bowl.

(Problems to be solved by the prior art and the invention) Toilets installed in public toilets, office buildings, etc. are used by an unspecified number of people, so they need to be clean and energy-saving. Water saving from the point of view,
It is also necessary to appropriately save electricity.

In recent years, many toilets have been fitted with not only cleaning devices but also odor evacuation pipes and their fans.If these could be driven automatically according to the use of the toilet, unnecessary fans could be eliminated. There is no need to drive or clean the equipment, which saves labor, and since these parts are driven reliably, the cleanliness improves.Furthermore, there is no need for the user to operate these parts, making them extremely convenient. It also becomes something.

Therefore, this invention was made in response to such a request.
The aim is to save labor, improve cleanliness,
It provides a very convenient toilet.

(Means and effects for solving the problems) In order to solve the above problems, the present invention provides a toilet in which an odor evacuation pipe 2 is attached to a toilet bowl l, and a fan 4 is attached to this odor evacuation pipe 2, In a device comprising one cleaning device 5,
A sensor 7 is provided to detect the presence of a person near the toilet bowl 1, and when a detection signal from the sensor 7 is output, the fan 4 is driven, and when the detection signal from the sensor 7 disappears, the cleaning device 5 is activated. It becomes like driving.

Further, in order to solve the above-mentioned problems, the present invention provides a toilet in which an odor evacuation pipe 2 is attached to a toilet bowl 11 provided in a booth 10, and a fan 4 is attached to this odor evacuation pipe 2. A first sensor 7a for detecting that a person is in the booth 10 and a second sensor 7b for detecting when the toilet bowl 11 is in use are provided. , the fan 4 is driven when a detection signal from the first sensor 7a is output, and the cleaning device 13 is driven after the use of the toilet bowl 11 is finished based on the detection signal from the second sensor 7b. .

According to the above configuration, the cleaning device and the fan are automatically driven in accordance with the use of the toilet, and these are driven accurately.

(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

Figure 1 shows a toilet equipped with a urinal, where 1 is a urinal and 2 is a toilet.
3 and 4 are dampers and fans attached to this urinal 1, 5 is a tank containing cleaning water constituting the cleaning device according to the present invention, and 6 is a It is a control panel equipped with a control circuit 6a (see FIG. 2), and a reflected light detection type sensor 7 is installed at a predetermined position on the front side of this control circuit 866 to detect when a person is standing in front of the urinal l. It is being

FIG. 2 is a block diagram showing these configurations, and the control circuit 6a opens the damper 3 using the damper switch 3a when a person stands in front of the urinal 1 based on the detection signal of the sensor 7. At the same time, the fan 4 is driven by the fan drive unit 4a, and when the detection signal disappears, the damper 3 is closed and the fan 4 is stopped.
At the same time, the tank 5, which is a cleaning device, is opened and the urinal 1 is cleaned.

At this time, the fan 4 is stopped by a timer 8 which is driven based on the detection signal of the sensor 7.
The process may be performed after a predetermined time has elapsed (slightly longer than normal use time) after a person is detected by the output signal of the user, or after a predetermined time has elapsed after a person is no longer detected. Even when the person is gone, the fan continues to operate for a while, and the odor can be sufficiently removed, and if there is a user later, the user can comfortably use the toilet.

FIG. 3 is a diagram showing another embodiment, and the same objects as in FIG. 1 are given the same numbers. In this embodiment, in a toilet equipped with a plurality of urinals 1, a sensor 7 for detecting a user is provided in front of each urinal 1, and these output signals are input to one control panel 6. However, if a user is detected in even one of the urinals 1..., the damper 3 is opened and the fan 4 is driven in the same way as in the previous embodiment; A damper 3, a fan 4, and a cleaning device 5 are shared by each urinal 1.

Note that 5a shown in this embodiment is a water supply device that is controlled by the control panel 6 and supplies a predetermined amount of cleaning water to the tank 75, and is omitted in FIG. In this embodiment, instead of each of the sensors 7, a sensor 9 is provided that detects whether or not there is a person in the entire toilet room, and a fan or the like is driven based on the output signal of the sensor 9. You may also do so.

Figure 4 is a diagram showing the toilet installed in the booth, with 10
11 indicates a booth, 11 indicates a toilet bowl, and other objects similar to those in FIG. 1 are given the same reference numerals. The sensor 7 in this embodiment is installed in a booth 10 as shown in FIG.
a first sensor 7a that detects that a person is inside;
As shown in FIG. 6, the second sensor 7b is capable of detecting the user only after the user sits on the toilet bowl 11, and the second sensor 7b detects when the toilet bowl 11 is being used. The block configuration of this embodiment is also substantially the same as that shown in FIG. Note that 12 in the figure indicates a cleaning switch for cleaning the toilet bowl 11 by the user's operation.

FIG. 7 is a flowchart showing the operation of such a toilet, and the operation will be explained below according to this flowchart. First, the first sensor 7a detects whether or not a person has entered the booth 10 [15]. If it is determined that the toilet has entered [15Y], the fan 4 is driven and the damper 3 is opened [16], and then, on the condition that the detection signal from the second sensor 7b disappears, it is determined that the use of the toilet has ended [ 17Y], flush valve 13 which is a cleaning device
The toilet bowl is flushed by activating it [18]. After that,
On the condition that the detection signal from the first sensor 7a disappears again, it is determined that the person has left the booth [19Y],
The fan 4 is stopped and the damper 3 is closed to complete the series of operations.

In addition, also in this embodiment, the stop of the fan 4 is as follows:
As in the embodiment described above, the driving may be stopped after a predetermined time has elapsed using a timer.

(Effects of the Invention) As is clear from the above description, according to the present invention, it is possible to automatically remove odors and clean them according to the use of the toilet bowl, thereby eliminating unnecessary cleaning and deodorizing. Moreover, this operation is performed reliably every time the toilet bowl is used, thereby making it possible to provide a toilet that saves energy, has a clean feeling, and is easy to use.
