Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a deodorant toilet device installed in a toilet room of a vehicle.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, as a deodorizing method in a toilet room of a vehicle, for example, as disclosed in JP-A-3-42372 and JP-A-3-104772, from a middle position between a toilet bowl and a waste tank in a vehicle equipped with a waste disposal device. The odor inside the filth tank and inside the toilet room was forcibly released to the outside of the vehicle by a blower device, and the odor was suppressed by introducing chemicals into the filth tank.

[0003]

[Problems to be solved by the device]

 However, according to the conventional deodorizing method, the air between the toilet room and the filth tank is insufficiently blocked, and therefore, even after use, the odor still remains in the toilet room, causing a discomfort to the user. was there.

[0004]

[Means for Solving the Problems]

 Therefore, the present application improves the deficiency of the conventional configuration by reliably blocking the air in the toilet room from the air in the waste tank and deodorizing the odor remaining in the toilet room. Is a deodorizing mechanism that forcibly circulates the air in the toilet room through the deodorizing filter, and an air blocking mechanism that can operate between an inoperative position that seals the toilet outlet and an operating position that opens the toilet outlet. The odor releasing mechanism is connected between the toilet bowl and the waste tank and forcibly discharges the air in the toilet room and the waste tank to the outside. Installed in the air conditioner, the front opening of which is open in the toilet room, the filter housing connected to it and containing the deodorizing filter, the first blower device connected to this, and the air supply port connected to it. The air cut-off mechanism consists of a circulation pipe that is guided indoors, and an air shutoff mechanism that reciprocates with pressurized air entering and exiting controlled by an electromagnetic valve, and an exhaust of the toilet bowl when the air cylinder moves forward through a link mechanism. It consists of a shut-off valve that opens the outlet and seals the outlet of the toilet when the air cylinder returns, and the odor emission mechanism connects one end to the air chamber inside the outer casing that connects the toilet and the waste tank. It is characterized by comprising a discharge pipe and a second blower device connected to the discharge pipe and communicating with the outside.

[0005]

[Action]

 When the user operates the toilet room, for example, when the push button is operated, the air cutoff mechanism operates from the inoperative position to the operating position to open the outlet of the toilet. In addition, the odor releasing mechanism also operates to forcibly release the air in the toilet room and the waste tank to the outside. If, for example, the push button is operated after the toilet has been operated in this state, the air shutoff mechanism will return to the inoperative position to seal the outlet of the toilet bowl, thereby shutting off the air in the toilet room and the air in the waste tank. , The odor release mechanism stops. Further, the deodorizing mechanism operates for a certain period of time, for example, about 5 minutes, and deodorizes and filters the odor remaining in the toilet room.

[0006]

【Example】

 With reference to the drawings, the embodiment of the present invention will be described in detail. FIG. 1 shows a configuration of a main part of a toilet bowl and a waste tank, and FIG. 2 shows an air cutoff state and a water-water separation configuration. As is well known, in the toilet room A, a toilet bowl 3 is installed on a tread 2 which is one step higher than the floor surface 1, and at the bottom of the tread 2, the air in the room is deodorized, filtered and circulated. A deodorizing mechanism 4 is installed. The deodorizing mechanism 4 is connected to the intake port portion 6 whose front surface opens at the rising surface 5 of the floor surface 1 and the tread 2, and the rear end thereof, and is provided with iron multi-holes inside the container made of, for example, fibrous activated carbon. The deodorizing filter 7 filled with the body and the chemical adsorbent is exchangeably housed in the filter casing 8, the first blower device 9 connected to the rear end of the deodorizing filter 7 and the air supply port thereof are connected to the tread 2. It consists of a circulation pipe 10 that passes through the room and opens at its upper position. As is well known, the toilet bowl 3 is provided with a frame edge 11 along the inner peripheral edge of the upper part thereof, and in this frame edge 11, a washing pipe 13 for washing with water having a nozzle 12 on the lower surface is arranged. The tip is connected to a water supply unit via a water washing pump 14.

The air shutoff mechanism 15 that shuts off the air in the toilet room A from the air in the waste tank 21 described later is a shutoff valve having a sealing piece 16 made of rubber or the like on the inner surface for sealing the outlet 3a of the toilet bowl 3. 17, an air-conditioner 19 whose pressurized air is controlled to flow in and out by a solenoid valve 18, and the discharge port 3a is opened when the air cylinder 19 moves forward, and the discharge port 3a is closed when the air cylinder 19 is returned. It is composed of a link mechanism 20 for operating the shutoff valve 17.

The toilet bowl 3 is provided with a tubular outer jacket 22 surrounding a lower outer periphery thereof and extending downward and having a lower end connected to a waste tank 21 by a mounting member 23. A tubular steam separator 24 is attached to the inside of 22. Further, an air chamber 25 partitioned by the outer jacket 22 and the air / water separator 24 is connected to one end of an air discharge pipe 27 constituting an odor emission mechanism 26, and the air discharge pipe 27 is connected to the outside. A second blower device 28 in communication is connected.

Therefore, for example, when the user enters the toilet room A and operates the solenoid valve 18 by a push button operation, the air cylinder 19 is moved forward by the supply of pressurized air in the forward direction, whereby the link mechanism 20 is moved. The shut-off valve 17 is operated from the inoperative position where the outlet 3a of the toilet bowl 3 is sealed to the operating position where the outlet 3a opens. Further, the second blower device 28 of the odor emission mechanism 26 operates to forcibly release the air in the toilet room A and the air in the waste tank 21 including the outer jacket 22 to the outside. In this state, when the solenoid valve 18 is moved back by pressing the push button, for example, by operating the push button operation, the coconut coiler 19 is actuated in the retracted direction by receiving the supply of pressurized air in the opposite direction, whereby the shut-off valve 17 returns to the inoperative position. It moves to close the outlet 3a, and the air in the toilet room A and the waste tank 21 including the outer jacket 22 is shut off. In addition, the second blower device 28 is stopped, and the first blower device 9 is operated for a certain period of time, for example, about 5 minutes, and the odor remaining in the toilet room A is deodorized and filtered by the filter mechanism 4, and the indoor odor is filtered. Is circulated to.

[0010]

[Effect of device]

 As described above, according to the present invention, in the use state, the air in the toilet room and the waste tank is forcibly released to the outside by the odor releasing mechanism, and after use, at the position of the outlet of the toilet bowl. The air in the toilet room and the air in the waste tank are shut off, and the odor remaining in the toilet room is deodorized and filtered for a certain period of time, so even small amounts of odor remaining in the toilet room can be reliably removed. It has the advantage of being able to
