[0001]

[Industrial applications]

 This invention relates to a deodorizing device for a toilet bowl.

[0002]

[Prior art]

 In recent years, a deodorizing device for deodorizing an odor generated in a toilet bowl is often incorporated in the toilet bowl. Conventionally, this type of deodorizing device guides the odor generated in the toilet bowl to the exhaust passage, and it also adsorbs and deodorizes activated carbon placed in the exhaust passage, decomposes ozone and deodorizes it using a photocatalyst In addition, various forms have been proposed and implemented, such as guiding the exhaust passage to the discharge pipe of waste water in the toilet bowl for deodorization.

[0003]

[Problems to be solved by the device]

 However, in the case of the conventional deodorizing device, there were specific problems depending on its form, such as the need to periodically replace the activated carbon and the deodorizing catalyst and the troublesome installation and construction of the device. .

[0004]

[Means for Solving the Problems]

 The invention of the present application has been made in view of such circumstances, and has been made in order to provide a deodorizing device having a novel form which is completely different from the conventional one. Thus, in the invention of the present application, the odor generated in the toilet is guided to the exhaust passage and exhausted, and at the same time, the endothermic portion connected to the endothermic side of the Peltier element is located on the exhaust passage, and the moisture contained in the exhaust gas is exhausted at the endothermic portion. The dew condensation water is used to deodorize the odorous components in the exhaust gas by the dew condensation water (Claim 1).

Further, another invention of the present application is characterized in that a discharge passage for discharging the condensed water to the toilet bowl is extended from the exhaust passage (claim 2).

[0006] Yet another invention of the present application is characterized in that the end of the exhaust passage is opened to the inside of the room (claim 3).

[0007]

[Action and effect of the device]

 As described above, in the invention of claim 1, the heat absorbing portion connected to the heat absorbing side of the Peltier element is arranged on the exhaust passage, the moisture in the exhaust is condensed here, and the odorous component is adsorbed in the condensed water. According to the present invention, deodorization is performed, and it is not necessary to regularly replace the adsorbents such as activated carbon and the deodorization catalyst, and it is not necessary to perform troublesome maintenance. Moreover, since it is not necessary to connect the exhaust passage to the discharge pipe of the toilet, the construction is simple.

According to the second aspect of the present invention, there is provided an outlet passage for guiding the condensed water generated on the exhaust passage. According to the present invention, the condensed water is guided to the toilet bowl and Since it can be discharged together with water, the treatment of condensed water becomes easy.

According to the third aspect of the present invention, the end of the exhaust passage is opened to the inside of the room. According to the present invention, dry air without water can be released to dehumidify the inside of the room. And are possible.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, 10 is a Western-style toilet bowl, 12 is a toilet bowl, 14 is a toilet seat, 16 is a toilet lid, 18 is a low tank, and 20 is a reservoir for flush water in the low tank 18.

Reference numeral 22 denotes a toilet deodorizing device, which has an exhaust passage 24 disposed inside the low tank 18. One end of the exhaust passage 24 is open toward the toilet bowl 12, and the other end is open indoors.

A blower fan 26 is disposed inside the exhaust passage 24, and the odor in the toilet bowl 12 is guided into the exhaust passage 24 based on the rotation of the blower fan 26, and is further circulated in the passage. It is like this.

In the exhaust passage 24, a Peltier element 28 is also arranged as shown in detail in FIG. As shown in the schematic diagram of FIG. 3, the Peltier element 28 is formed by disposing an N-type semiconductor 34, an intermediate electrode 36, and a P-type semiconductor 38 between positive and negative electrodes 30 and 32. When a direct current is passed through the negative electrodes 30 and 32, the positive and negative electrodes 30 and 32 generate heat, and the intermediate electrode 36 absorbs heat. If the direction of energization is reversed, the opposite phenomenon occurs, that is, the positive and negative electrodes 30 and 32 absorb heat, and the intermediate electrode 36 generates heat.

A heat absorbing fin 40 extends from the heat absorbing side of the Peltier element 28, and the heat absorbing fin 40 is exposed in the exhaust passage 24. Below the heat absorbing fins 40, a discharge passage 42 is branched from the exhaust passage 24. The leading end of the outlet passage 42 is open inside the toilet bowl 12.

Next, the operation of the deodorizing device of this example will be described. When the blower fan 26 is rotated, the air in the toilet bowl 12 is introduced into the exhaust passage 24 together with the odor as described above, and is circulated through the exhaust passage 24.

Since the Peltier element 28 is arranged in the exhaust passage 24, when the Peltier element 28 is in the operating state, the water in the air flowing through the exhaust passage 24 is cooled here. Reaching the dew point and forming water drops as shown in FIG. That is, the heat absorbing fins 40 are cooled to cause dew condensation.

When the water droplets 44 adhere to the heat absorbing fins 40 in this way, the odorous components in the air flowing through the exhaust passage 24 are adsorbed by the water droplets and removed from the exhaust gas. Immediately, deodorization is performed here. Then, it is discharged indoors from the end of the exhaust passage 24 in a cleaned state.

On the other hand, the water droplets 44 attached to the heat absorbing fins 40 grow into larger water droplets, and then drop from the heat absorbing fins 40 when they reach a certain size. The dropped water is guided to the outlet passage 42 and discharged to the toilet bowl 12, and is discharged to the outside through the discharge pipe 46 for discharging the dirty water together with the water in the toilet bowl 12.

The deodorizing device 22 of the present example has a feature of dehumidifying the interior of the room in addition to the deodorizing effect, since the moisture in the air is removed from the exhaust passage 24 and the air is released into the room from the end thereof. is doing.

The embodiment of the present invention has been described in detail above, but this is merely an example, and the present invention can be configured in a form in which various modifications are made based on the knowledge of those skilled in the art without departing from the spirit of the present invention. .
