Abstract

PURPOSE:To raise the utility of deodorizing stool by a method in which the blow-out pressure of deodorizing fan, always higher than back pressures, when the deodorizing stool is being used, is sent out. CONSTITUTION:A deodorizing box 7 is detachably set on the rear upside 3 of a stool body (a), in which a deodorizing fan 6a, a valve 6c, and a pressure sensor 6d are built. In a controller, the blow-out pressure of the fan 6a is set up in advance and back pressure values from a drain 8, detected by the sensor 6d, are compared with the blow-out pressures. When the back pressure value is higher than the blow-out pressure value, the revolving number of the fan 6a is increased through an inverter to increase the blow-out pressure of the fan 6a beyond the back pressure.

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a deodorizing toilet that exhausts odor within the toilet pole to a discharge section.

(Prior art) Conventionally, this type of deodorizing toilet has one end facing the bowl of the toilet, and the other end facing the drain pipe inside the toilet body, as described in Japanese Utility Model Application Publication No. 645981, for example. Some devices have a deodorizing path facing toward the deodorizing device, and are equipped with a deodorizing fan and an on-off valve downstream of the fan that opens and closes the deodorizing path in conjunction with turning on and off the fan.

(Problem to be solved by the invention) However, the purpose of deodorizing toilets is to remove odors from inside the bowl part during use, and in order to prevent backflow of odors due to back pressure, the fan This was enough to prevent the backflow of odor by closing the opening/closing valve in conjunction with turning off the fan when not in use.

Therefore, if back pressure is applied while the deodorizing fan is operating, the blowing pressure of the fan will be weakened, resulting in poor deodorizing efficiency.
It could not be said that it was sufficiently effective as a deodorizing toilet, leaving room for improvement.

The present invention was made in view of the problems of the prior art, and its purpose is to always deliver a blowing pressure of the deodorizing fan that is higher than the back pressure when the deodorizing toilet is in use. , to make it more effective as a deodorizing toilet.

(Means for Solving the Problems) The technical means achieved by the present invention to achieve the above object is to form a deodorizing path that leads to the bowl part of the toilet bowl at one end and to a desired discharge part at the other end. and a deodorizing toilet provided with a deodorizing fan in the deodorizing passage and an on-off valve that opens and closes the deodorizing passage in conjunction with turning on and off of the fan downstream of the fan, the deodorizing toilet being disposed on the downstream side of the on-off valve. a pressure sensor that detects a back pressure value from the discharge section; and a control section that sets a positive blowout value of the deodorizing fan; The aim is to output a blowing pressure greater than the back pressure value when the back pressure value is greater than the back pressure value.

Further, a control unit is connected to a pressure sensor and a deodorizing fan, and the control unit compares a back pressure value detected by the pressure sensor with a set positive blowout value to adjust the rotation speed of the deodorizing fan. You can also use it as

Further, the control section is connected to a damper and a pressure sensor arranged between the on-off valve and the deodorizing fan, and the control section compares the back pressure value detected by the pressure sensor with the set positive blowout value. It is also possible to adjust the opening degree of the bolts.

When back pressure from the discharge section is applied during this odor exhaust, a pressure sensor placed downstream of the on-off valve detects the back pressure value and sends the signal to the control section, which detects the back pressure value. It is compared with a preset positive blowing value, and when the back pressure value is larger, the blowing pressure is controlled to be larger than the back pressure value.

Also, when the control unit is connected to the pressure sensor and the deodorizing fan, if the back pressure value detected by the pressure sensor and sent to the control unit is larger than the set positive blowing value of the deodorizing fan, The rotation speed of the deodorizing fan is adjusted so that the blowing pressure is greater than the back pressure value.

I will contact you.

Note that the on-off valve 6c is merely an example, and is not limited as long as it is electrically operated. .

In the control unit (not shown), the three values of the blowout of the deodorizing fan 6a are set in advance, and the back pressure value from the drainage channel (discharge portion) 8 detected by the pressure sensor 6d is set as the three values of the blowout. When the back pressure value is larger than the three blowout values, the number of revolutions of the deodorizing fan 6a is increased via an inverter or the like (not shown) to increase the blowout pressure of the deodorizing fan 6a to the back pressure. Make it larger than the pressure value.

The deodorizing fan 6a may be started automatically upon detection by a human body detection sensor (not shown) placed on the toilet body a or the wall of the toilet room, or may be started manually by the toilet user. do.

Therefore, as shown in FIG. 5, when the human body detection sensor detects the seating (5-1), the deodorizing fan 61 is turned on and the on-off valve 6c is opened (5-2), causing the odor inside the ball part 1 to be removed. is sucked into the odor passage 5 from the odor intake 4, passes through the deodorizing box 7, passes through the exhaust passage 9, and is exhausted into the drainage passage 8. When the human body is detected to have left the seat after defecating (5- 3) After operating the deodorizing fan 6a for a certain period of time (5-4), the deodorizing fan 6a is turned off and the on-off valve 6c is closed (5-5).

If back pressure is applied from the drainage channel 8 during the odor exhaustion, the tip of the detection part of the pressure sensor 6d detects the back pressure.
” detects it and sends it to the control unit (not shown).

Then, when the back pressure value sent from the pressure sensor 6d is compared with the preset positive blowing value of the deodorizing fan 6a (5-6), when the back pressure value is larger than the positive blowing value (5-6), the back pressure value is larger than the positive blowing value (5-6). -6"), and the rotation speed of the deodorizing fan 6a is increased via an inverter etc. according to a signal from the control unit (
5-7) The blowing pressure of the deodorizing fan 6a is made larger than the back pressure to push back the backflow odor.

It is also possible to provide an LED level meter so that the current deodorizing air volume can be displayed and visually checked, and the level meter can also be used to determine whether or not the deodorizing fan 6a is out of order.

Furthermore, the deodorizing box 7 may be provided with an ozone deodorizing device, an optical deodorizing device, or the like.

Further, the structure of the deodorizing box 7 that is freely removable may be a generally known structure. For example, although not shown in the drawings, the deodorizing box 7 is formed to a size that can be fitted into the space 10, and a fit-in type is used. Alternatively, a protrusion may be provided at a desired position on the inner bottom surface (rear upper surface) 3 of the space 10, and a recess may be provided at a desired position on the bottom plate of the deodorizing box cover opposite to the protrusion, or a fitting type may be provided. Both sides 1[1a of 10, grooves parallel to the IOa surface are provided, and both side surfaces 7c, 7c of the deodorizing box 7 are provided.

The damper 6g is, for example, a rotary solenoid 6g'
This is a conventionally known device that electrically moves up and down, etc., and is connected to a control section that is connected to the pressure sensor 6d.

Therefore, when back pressure is generated from the drainage channel 8, the detection section 6d' of the pressure sensor 6d detects the back pressure and sends it to the control section.

Then, compare the back pressure value sent from the pressure sensor 6d with the preset blowout pressure (6-6), and when it is determined that the back pressure is large (6-6°), send a signal to the inverter, The opening degree of the damper 6g is widened (6-7) to increase the amount of deodorizing air flowing through the communication pipe 6b and increase the blowing pressure, pushing the backflowing odor back to the exhaust path 8 and preventing the backflow of the odor to the ball part 1. (See Figures 4 and 6).

Note that the other configurations and effects are the same as in the case of controlling the deodorizing fan 6a, and the explanation thereof will be omitted.

Furthermore, it is also possible to control the deodorizing fan 6a and the damper 6g at the same time.

The fan is ON, O
In a deodorizing toilet equipped with an on-off valve that opens and closes the deodorizing passage in conjunction with FF, a pressure sensor arranged downstream of the on-off valve detects a back pressure value from the discharge section, and a pressure sensor that detects a back pressure value from the discharge section; Even if back pressure occurs while the toilet is in use, a pressure sensor detects the back pressure from the discharge section downstream of the on-off valve, and the detected back pressure value is transmitted to the control section. and adjust the blowing pressure when it is determined that the back pressure value is larger than a preset positive blowing value,
Since a blowing pressure greater than the back pressure value is sent out, a reliable deodorizing function can be achieved, and the deodorizing toilet can be sufficiently effective, resulting in high reliability and increased commercial value.

In addition, when the control unit is connected to the deodorizing fan, when it is determined that the back pressure value detected by the pressure sensor is larger than the positive blowout value set in advance in the control unit, the control unit controls the rotation speed of the deodorizing fan. is adjusted to send out a blowing pressure greater than the back pressure value, so the same effect as described above can be achieved.

Furthermore, when a damper is disposed between the on-off valve and the deodorizing fan and a control unit is connected to the damper and the pressure sensor, the back pressure value detected by the pressure sensor is set to a predetermined value set in advance in the control unit. When it is determined that the blowout pressure is greater than the positive blowout value, the opening degree of the damper is increased to send out a blowout pressure of the deodorizing fan that is greater than the backpressure value, so that the same effect as described above can be achieved.
