Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a technique for using a fan and a heater used for drying warm air in a shower toilet even when deodorizing.

[0002]

[Prior Art]

 Conventionally, a technique for cleaning the odor in a toilet bowl through a deodorizing device and discharging the odor has been publicly known. For example, it is a technique disclosed in Japanese Utility Model Publication No. 1-37021 and Japanese Utility Model Publication No. 2-132779. In the former technique, the suction port and the discharge port are opened in the toilet bowl and communicated with each other by a duct, the intake port and the discharge port are opened outside the toilet bowl in the middle of the duct, and dampers are arranged at the respective openings. A deodorant, a fan, and a heater are sequentially arranged in the duct, and at the time of urination, the damper of the outlet is opened to close the outlet to deodorize the odor in the toilet and discharge it to the outside of the toilet. Was configured to open the intake port, close the intake port, close the exhaust port, and blow warm air locally. In the latter, the suction port is opened inside the toilet, the blow-out port is opened outside the toilet at the foot side, the suction port and the blow-out port are connected by a duct, and a fan and heater are placed in the duct, and inside the duct. The ozone generator was faced to remove the odor when exhausting air and sending warm air to the feet.

[Problems to be solved by the device]

 However, in the former technology, since two openings are provided in the middle of the duct and dampers are provided in each, the opening and closing operation of the damper is troublesome, the structure of the duct becomes complicated, and the temperature detection means is placed inside the duct. Therefore, when the toilet is used subsequently, the accurate room temperature cannot be detected, and the heater may become too hot. In the latter case, the hot air is to be discharged to the feet in the summer, which is hot and uncomfortable, and it was necessary to install a separate fan for hot air drying. Therefore, the present invention intends to enable heating of the feet and local hot air drying with a simple structure at an appropriate temperature in consideration of room temperature and the like.

[0004]

[Means for Solving the Problems]

 In order to solve such a problem, the present invention provides a duct that connects the inside and outside of a toilet of a shower toilet, and arranges a heater, a fan, and a deodorizing device in that order from the inside of the toilet. Is configured to be switchable between forward and reverse when drying and deodorizing. Alternatively, the heater, the fan blades, the deodorizing device, and the fan motor are sequentially arranged in the duct from the inside of the toilet, and the fan can be switched between forward and reverse rotation.

[0005]

[Action]

 At the time of urination, the fan is rotated forward to guide the odor in the toilet into the duct, deodorized by the deodorizer and discharged to the outside of the toilet. At this time, when the room temperature is low, the heater is activated to send warm air to the feet. Thus, when drying after washing, the fan is reversed and the heater is operated to perform warm air drying.

【Example】

 The problems to be solved and the means for solving the present invention are as described above. Next, the embodiment shown in the attached drawings will be described. FIG. 1 is a perspective view of a Western-style toilet equipped with the deodorizing device of the present invention. 2 is the same front view, FIG. 3 is the same plan view, and FIG. 4 is a partial front sectional view showing the deodorizing mechanism of the present invention.

To explain the overall configuration in FIGS. 1, 2, and 3, a bowl portion 1a is formed in the front portion of the toilet bowl 1, and a toilet seat 2 and a toilet lid 3 are rotatably mounted on the bowl portion 1a around the rear portion. Is provided, the low tank 4 is fixed on the rear part of the toilet 1, the washing handle 5 is arranged on the side surface of the low tank 4, and when the washing handle 5 is rotated, the float valve in the low tank 4 is opened. The water in the raw tank 4 flows into the bowl portion 1a and is discharged. Then, a ball tap connected to the water supply pipe 10 and a float (not shown) are internally provided in the low tank 4, and when the water in the low tank 4 is discharged, the float is lowered so that the valve can be opened to supply water. When a certain amount of water collects in the low tank 4, the water supply is stopped by a ball tap.

The toilet seat 2 and the toilet lid 3 are pivotally supported by a mounting case 6 provided in the lower front portion of the low tank 4, and an operation box 6a is arranged on one side of the mounting case 6 and a butt is placed on the operation box 6a. A washing switch 20, a bidet washing switch 21, a hot air drying switch 22, a stop switch 23, a pressure adjusting dial 24, a temperature adjusting switch, etc. are provided, and a controller 19 is installed inside the operation box 6a. Is connected to control a valve, a pump, a fan 13, which will be described later, and the like, and a cleaning nozzle 9 is arranged in the center of the mounting case 6 so that the cleaning nozzle 9 can be withdrawn and withdrawn. 6 A duct 11 is installed from the center to the side of the other side to communicate the inside and outside of the toilet bowl.

As shown in FIG. 4, the duct 11 is provided with an outer opening 11a at one end on the outside of the toilet 1 toward the lower foot of the toilet front side, and the other end of the duct 11 is at the center of the mounting case 6 at the toilet bowl. 1, an inner opening 11b is provided, an opening 11c is opened outside in the middle of the duct 11, and a damper 15 is provided in the opening 11c to operate the motor 15a to open the opening 11c. It can be opened and closed. Inside the duct 11, a heater 12, a fan 13, a deodorizing device 14, and a temperature sensor 17 are sequentially arranged and installed inside, and a temperature sensor 16 for detecting the temperature inside the room is arranged outside the duct to operate the fan 13. The motor 13a for reversing is reversible, and the deodorizing device 14 deodorizes using activated carbon, ozone, light, etc., the heater 12, the motor 13a of the fan 13, the temperature sensors 16 and 17, and the damper 15 described above. The motor 15a and the human body detection sensor 25 (or the deodorizing device 14 when electrically operated) are connected to the controller 19.

Further, as shown in FIG. 5, the position of the deodorizing device 14 can be provided between the blade 13b of the fan 13 and the motor 13a, in which case ammonia gas contained in the odor is removed. As a result, the motors 13a and 15a can be prevented from deteriorating, and when the deodorizing device 14 is regenerated, the regeneration efficiency is high because it is close to the heater. When sending the warm air to the feet, there is no odor even immediately after use. Moreover, the wind force can be adjusted by the damper 15.

In such a structure, when a person approaches for convenience, a signal is sent from the human body detection sensor 25 to the controller 19 so that the damper 15 operates so as to close the opening 11c and operates the fan 13. The odor in the bowl 1a is sucked through the inner opening 11b, the odor is removed by the deodorizing device 14, and the odor is discharged from the outer opening 11a to the outside of the toilet 1 as indicated by arrow A. At this time, when the room temperature is low, the temperature sensor 16 operates the heater 12 to send warm air to the feet, and when the room temperature is high, the fan speed is increased by only the airflow to make the room cooler and more comfortable. The temperature sensor 17 detects the temperature so that it is not too hot.

Then, after the toilet is pushed, the washing switch 20 (21) is pushed to perform washing by the washing nozzle 9, and then the warm air drying switch 22 is pushed, the fan 13 is reversed and the heater 12 is operated, and the damper 15 is activated. The deodorizing device 14 is rotated and closed, the opening 11c is opened, the outside air is sucked, and the air is blown out from the inner opening 11b as shown by an arrow B. The strength of the warm air can be controlled by controlling the rotation speed of the fan 13 or by adjusting the angle of the damper 15. This is done by pressing the stop switch 23 to wash the toilet after drying, but if the deodorizing device 14 can be regenerated by heat, after the human body detection sensor 25 is turned off, or after use, It is configured to count the number of times when the number of times is performed and to close the opening 11c to raise the temperature of the heater 12 to operate the fan 13 to send hot air to the deodorizing device 14 for regeneration when there are no people at a certain rate. It is also possible.

[Effect of the device]

 Since the present invention is configured as described above, it has the following effects. In other words, when deodorizing and drying with warm air, the fan is only switched between normal rotation and reverse rotation, so only one fan is required, and the configuration of the duct that houses the fan and heater can be simplified, and cost reduction can be achieved. You can also warm your feet when deodorizing. Also, when the deodorizing device can be regenerated by heat, it can be regenerated by sending hot air to the deodorizing device.

Further, in addition to the above effects, ammonia gas and the like contained in the odor at the time of deodorization is removed by the deodorizing device, and is adsorbed by an adsorbent such as activated carbon, ozone, etc. If so, it will be disassembled and clean air will hit the motor, which will prevent it from corroding.
