The toilet for pets that shields the odor gas generated from manure by the box to reduce the surrounding pollution, because the odor gas generated from the manure stays in the box at a high concentration. As a result, the high-concentration odor gas in the box leaks out of the box, and there is dissatisfaction that the periphery of the box is contaminated with the odor gas.

A pet toilet designed to shield the odorous gas generated from manure by the box and reduce the surrounding contamination. Because the odorous gas generated from the urine stays in the box at a high concentration, There is dissatisfaction that odor is emitted by high-concentration odor gas and manure odor is emitted from pets.

The toilet for pets that shields the odor gas generated from manure by the box and reduces the surrounding contamination. Since the odor gas generated from the urine stays in the box at a high concentration, the upper box is removed by cleaning etc. At this time, the high-concentration odor gas staying in the box is released all at once, and there is dissatisfaction that the periphery of the box is remarkably contaminated by the high-concentration odor gas.

In addition to shielding the odor gas generated from manure by the box to reduce the surrounding contamination, the toilet for pets that reduces the concentration of odor gas retained in the box by providing an odor gas treatment agent etc. Since the odor gas that has been generated and accumulated in the box is sequentially processed, the odor gas concentration in the box can be reduced, but it does not eliminate odor gas retention. The complaint that pets leak out of the box and the area around the box is contaminated with odorous gas cannot be resolved.

In addition to shielding the odor gas generated from manure by the box to reduce the surrounding contamination, the toilet for pets that reduces the concentration of odor gas retained in the box by providing an odor gas treatment agent etc. Since the odor gas that has been generated and accumulated in the box is sequentially processed, the odor gas concentration in the box can be reduced, but it does not eliminate odor gas retention. The dissatisfaction that odors are emitted and the odor of manure diverges is not resolved.

In addition to shielding the odor gas generated from manure by the box to reduce the surrounding contamination, the toilet for pets that reduces the concentration of odor gas retained in the box by providing an odor gas treatment agent etc. This is a sequential process of odor gas generated and retained in the box, so the odor gas concentration in the box can be reduced, but it does not eliminate odor gas retention, so when the upper box is removed by cleaning etc. The odor gas staying in the body is released at once, and the dissatisfaction that the periphery of the box is contaminated with the odor gas is not solved.

In addition to shielding the odor gas generated from manure by the box to reduce the surrounding contamination, the pet toilet that inhales and discharges the odor gas to the outside through the hole communicating with the outdoors provided at the upper end of the pet toilet body hood However, since most of the air flowing in from the opening passes through the box without being involved in the discharge of odor gas emanating from manure on the receptacle in the box, there is a lot of wasteful dissatisfaction with exhaust.

In addition to shielding the odor gas generated from manure by the box to reduce the surrounding contamination, the pet toilet that inhales and discharges the odor gas to the outside through the hole communicating with the outdoors provided at the upper end of the pet toilet body hood Because exhaust gas is wasteful, if the exhaust amount is not increased, odor gas diffuses and stays inside the box, and the odor gas stays outside the box, causing dissatisfaction that the area around the box is contaminated with odor gas. is there.

In addition to shielding the odor gas generated from manure by the box to reduce the surrounding contamination, the pet toilet that inhales and discharges the odor gas to the outside through the hole communicating with the outdoors provided at the upper end of the pet toilet body hood Because there is a lot of waste in exhaust, if the exhaust amount is not large, the odor gas diffuses and stays in the box, and the pet used for stool is odorized by the stayed odor gas, and there is dissatisfaction that manure odor emits .

A pet toilet that inhales and discharges odorous gas in the pet toilet body to the outside has a dissatisfaction that a hole must be made in the outer wall or the like in order to discharge the gas in the box to the outside.

The pet toilet that inhales and discharges the odor gas inside the pet toilet body is connected to the duct to discharge the odor gas inside the box to the outside. There is dissatisfaction restricted in the vicinity.

A pet toilet that inhales and discharges odor gas in the pet toilet body to the outside is unsatisfactory because odor gas is contaminated outdoors.

In addition to shielding the odor gas generated from manure by the box to reduce the surrounding contamination, the pet toilet that inhales and discharges the odor gas to the outside through the hole communicating with the outdoors provided at the upper end of the pet toilet body hood If the upper box is removed by cleaning or the like, the function of exhausting the odor gas generated from manure is lost, and there is dissatisfaction that the odor gas is released at once and the periphery of the box is contaminated with odor gas.

This invention is made in view of such a point, and makes it a subject to provide the pet toilet which can prevent the odor gas pollution of the periphery by the leak of odor gas, and the odor to the pet to use. .

The present invention is based on the general principle that pollution prevention is more effective as it is performed closer to the source. Based on the general principle, an appropriate air flow is generated in the toilet for pets, and odorous gas emanating from manure is generated from the floor near the source. Eliminates stagnant odor gas due to the structure that discharges to the bottom of the surface, and eliminates odor gas contamination in the surroundings due to leakage of odor gas in pet toilets and odors on pets due to odor gas in pet toilets It is.

A conventional pet toilet that inhales and discharges odorous gas to the outside exhausts air from a hole that communicates with the outdoors provided at the upper end of the pet toilet body hood, and generates an airflow shown in the vector diagram of FIG. For this reason, most of the gas flowing in from the opening of the box passes through the box without being involved in the discharge of odorous gas emanating from manure on the floor in the box.

The pet toilet of the present invention that exhausts odorous gas by passing it through the ventilated and water-permeable floor surface generates the airflow shown in the vector diagram of FIG. 2, and odorous gas emitted from manure on the floor diverges. As a result of the odor gas being exhausted from the immediate vicinity of the source of emission to the lower part of the floor due to the airflow facing in the direction of the odor, the odor gas does not stay in the box, so there is no odor gas contamination inside the box and the odor gas outside the box It is possible to eliminate the leakage of odor and the odor of the pet used in the pet toilet.

Since the airflow in the box of the pet toilet according to the present invention flows when fresh gas comes into contact with the urine, drying of the urine is promoted, and generation of odor gas can be suppressed.

The conventional pet toilet that exhausts from the hole communicating with the outside provided at the upper end of the main body hood of the pet toilet loses the exhaust effect completely when the main body hood is removed by cleaning etc., and the box body is contaminated with odor gas There are complaints to be made.

In the structure that exhausts from the top of the floor, even if the odor gas suction part is installed and fixed at the end of the floor, the air flow shown in the vector diagram of Fig. 3 is generated when the upper box is removed by cleaning or the like. Therefore, it cannot be expected to suppress the odor pollution around the exhaust.

The pet toilet of the present invention having a structure that exhausts air through a ventilated and water-permeable floor generates the air current shown in the vector diagram of FIG. 4 even when the upper box is removed, thereby discharging odor gas. The function to hold is maintained, and even when the upper box body is removed by cleaning or the like, contamination around the box body due to odor gas can be suppressed.

The pet toilet according to claim 2 has a built-in gas treatment tank for treating odor gas, so that it is not necessary to exhaust the odor gas emanating from manure to the outside, and there is no need to make a hole in the outer wall or the like.

The pet toilet according to claim 2 does not require connection of a duct for exhausting odor gas to the outside, so there is no need to place the pet toilet near the hole opened in the outer wall, and the pet toilet has excellent installation and mobility. Can provide toilets.

The pet toilet according to claim 2 does not exhaust the odor gas emanating from manure to the outdoors, so that no odor gas contamination occurs outdoors.

The pet toilet according to claim 3 generates the air flow shown in the vector diagram of FIG. 5, and the odor gas from the floor near the divergence source is generated by the air flow opposed to the direction in which the odor gas emanating from the manure on the floor is emitted. By exhausting to the lower part of the surface, odor gas does not stay in the box, so there is no odor gas contamination in the box, leakage of odor gas outside the box, and attachment to pets used in pet toilets. The odor can be removed from the cause.

The pet toilet according to claim 3 has a structure in which the whole or a part of the processing gas processed through the gas processing tank is returned and circulated into the pet toilet box so that the processing gas discharged to the outside of the pet toilet is discharged. The amount of can be reduced.

The present invention generates an appropriate air flow in the pet toilet and discharges the odor gas from the vicinity of the generation source to the lower part of the floor by the air flow facing the direction in which the odor gas emanating from the urine in the pet toilet is emitted. As a result of the structure, odor gas does not stay in the pet toilet, so there is no odor gas contamination inside the box, odor gas leaking out of the box and surrounding odors and odors on pets used for stool In addition to being able to eliminate this from the cause, it is possible to provide a pet toilet with excellent installation and mobility.
