Description

Technical Field

[0001] The utility model relates to the technical field of toilet cleaning, in particular to a bottom exhaust type deodorizing toilet. Background Art

[0002] Existing rural toilets have poor ventilation and exhaust, making it difficult for odors to dissipate. This is especially true for dry toilets without flushing systems, which can cause severe odors, especially in the summer when the odor is strong and mosquitoes are common. Failure to ventilate and exhaust the toilets in a timely manner can lead to hygienic problems for people using the toilet.

[0003] Currently, toilet ventilation typically involves installing an exhaust fan on top of the toilet, which exhausts odors from the inside to the outside. This ventilation system can easily cause odor backflow from septic tanks or composting rooms. Because the odor generated by people using the toilet is located in the lower part of the toilet, by the time the exhaust fan kicks in, the odor has already spread throughout the entire toilet. Some toilets use fragrances for deodorization, but these only mask the odor, not completely reducing it. Furthermore, fragrances are chemical substances, and long-term use can cause health problems.

[0035] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0036] The following combination Figures 1 to 2 , the down-exhaust deodorizing toilet provided by the embodiment of the utility model is described in detail through specific embodiments and application scenarios.

[0037] like Figure 1 As shown, this embodiment provides a downdraft deodorizing toilet, comprising: a toilet room 1, a toilet bowl 2, a septic tank 3 and a ventilation system 4.

[0038] The toilet 2 is arranged at the bottom of the toilet house 1, and the septic tank 3 is arranged at the lower side of the toilet house 1, and the septic tank 3 is connected to the toilet 2.

[0039] The ventilation system 4 includes an exhaust duct 41 , an exhaust pipe 42 , an exhaust fan 43 and a supply fan 44 .

[0040] The exhaust pipe 42 is arranged on the outer wall of the toilet house 1 along the height direction of the toilet house 1, the first end of the exhaust pipe 42 is arranged at the top of the toilet house 1, and the second end of the exhaust pipe 42 is connected to the septic tank 3.

[0041] One end of the exhaust pipe 41 is connected to the bottom of the toilet room 1 to absorb the odor in the toilet room 1, and the other end of the exhaust pipe 41 is connected to the second end of the exhaust pipe 42.

[0042] The exhaust fan 43 is disposed on the inner side of the second end of the exhaust pipe 42 . The exhaust fan 43 is used to suck the odor in the exhaust pipe 41 and discharge it into the exhaust pipe 42 .

[0043] The blower 44 is provided in the toilet room 1 , and is used to supply air to the toilet room 1 .

[0044] It is understandable that toilets in rural areas include toilets with flushing systems and dry toilets without flushing systems. The toilets 2 in toilets with flushing systems can be squat toilets, flush toilets and urinals, while the toilets 2 in dry toilets only include squat toilets.

[0045] The toilet house 1 includes a top surface, a bottom surface and a peripheral wall. The toilet house 1 is used to isolate an independent space and accommodate a toilet 2. The septic tank 3 is used to treat and store toilet excrement. The septic tank 3 is connected to the toilet 2 through an excretion pipe.

[0046] The exhaust pipe 41 is used to collect odor from the bottom of the toilet house 1. The connecting port between the exhaust pipe 41 and the toilet house 1 can be set to one or more. Since the toilet 2 is set at the bottom of the toilet house 1, the odor is also located at the bottom of the toilet house 1 when people use the toilet. The exhaust pipe 41 collects odor from the bottom of the toilet house 1 and can remove the odor before the odor spreads to the human nasal cavity, reducing the odor sensation when the human body uses the toilet. This embodiment adopts a downward exhaust method to suck out the odor, which can deal with the odor in time before the odor spreads to the entire toilet house 1 space. Compared with the exhaust method from the top of the toilet house 1, the downward exhaust suction method can deal with the odor more quickly, with better effects, and brings greater comfort to the human body.

[0047] Specifically, the exhaust pipe 42 can be a round pipe or a square pipe. The exhaust pipe 41 can be a round pipe or a square pipe.

[0048] Furthermore, the exhaust fan 43 is used to generate suction force to draw the odor in the exhaust pipe 41 from the toilet room 1 to the septic tank 3 and discharge it to the exhaust pipe 42. Optionally, the exhaust fan 43 can be an axial flow fan or a centrifugal fan.

[0049] The blower 44 is used to supply air into the toilet room 1. Fresh air is supplied from the gaps between doors and windows and from the blower 44, replenishing the indoor air sucked in by the exhaust fan 43. In addition, the blower 44 blows air toward the bottom of the toilet room 1, forming an air curtain at the bottom of the toilet room 1, preventing odors from rising and further slowing the time it takes for odors to enter the human nasal cavity.

[0050] Specifically, the blower 44 may be a blower fan.

[0051] In this embodiment, when a person uses the toilet, the exhaust fan 43 is activated, and foul odors pass through the exhaust pipe 41 at the bottom of the toilet room 1 and, under the suction of the exhaust fan 43, enter the exhaust pipe 42 and are discharged from the top of the toilet room 1. At the same time, the blower 44 blows air into the toilet room 1, replenishing the air in the toilet room 1 in a timely manner and preventing foul odors from escaping.

[0052] The utility model provides a downward exhaust deodorizing toilet, which is equipped with a downward exhaust ventilation system 4 in the toilet house 1, and the interface between the exhaust pipe 41 and the toilet house 1 is arranged at the bottom of the toilet house 1, and an exhaust fan 43 is arranged in the exhaust pipe 42 to suck the odor in the exhaust pipe 41 and discharge it to the exhaust pipe 42, and discharged from the top of the toilet house 1. In addition, a blower 44 is arranged in the toilet house 1 to supply air to the toilet house 1, so that the air convection in the toilet house 1 can achieve better ventilation effect and increase the comfort of using the toilet.

[0053] In some embodiments, as Figure 1 and Figure 2 As shown, an exhaust port 11 is provided in the toilet room 1 of this embodiment, and the exhaust port 11 is communicated with the exhaust pipe 41.

[0054] There are multiple exhaust ports 11, and the multiple exhaust ports 11 are arranged at intervals.

[0055] It is understandable that a plurality of exhaust ports 11 are provided at the bottom of the toilet room 1, and the plurality of exhaust ports 11 can simultaneously extract odor, thereby speeding up the extraction speed of the odor and improving the efficiency of the odor extraction.

[0056] Specifically, in this embodiment, three exhaust ports 11 are provided around the toilet 2. The three exhaust ports 11 are provided on three sides of the toilet 2. The three exhaust ports 11 can simultaneously extract odor from three sides of the toilet 2, and the effect of extracting odor is better.

[0057] In some embodiments, as Figure 2 As shown, the exhaust port 11 of this embodiment is arranged on the ground.

[0058] It is understandable that the exhaust port 11 can be set on the floor of the toilet room 1, and the exhaust pipe 41 extends into the exhaust port 11 from the lower end of the floor of the toilet room 1 and is connected with the exhaust port 11. Under the action of the exhaust fan 43, the odor is sucked in from the exhaust port 11 on the ground and discharged into the exhaust pipe 41. Since the ground is the lowest, the odor suction effect is better.

[0059] The three exhaust ports 11 of this embodiment are provided on the ground at three sides of the toilet 2 to extract odor from three directions of the toilet 2 .

[0060] In some embodiments, the exhaust port 11 is provided on a wall.

[0061] It is understandable that the exhaust port 11 can also be set on the wall near the toilet 2. The exhaust port 11 is located on the wall close to the ground, and the exhaust pipe 41 extends into the exhaust port 11 from the outside of the wall of the toilet room 1.

[0062] In some embodiments, some of the plurality of exhaust ports 11 are disposed on the ground, and the rest are disposed on the wall.

[0063] It is understandable that multiple exhaust ports 11 can be provided, and multiple exhaust ports 11 are distributed around the toilet 2. Some exhaust ports 11 are provided on the ground around the toilet 2, and some exhaust ports 11 are provided on the walls around the toilet 2. The exhaust ports 11 on the ground and the walls jointly suck out the odor, forming a three-dimensional suction layout, which speeds up the odor suction.

[0064] In some embodiments, as Figure 2 As shown, the exhaust port 11 of this embodiment is a grille-type exhaust port.

[0065] It is understandable that the grille-type exhaust port is composed of a series of parallel or crossed metal or plastic strips, which can prevent large particles from entering the exhaust pipe 41 and blocking the exhaust pipe 41. In addition, the grille-type exhaust port can conveniently remove dust and debris and is easy to maintain.

[0066] In some embodiments, as Figure 2 As shown, the exhaust port 11 is a louvered exhaust port.

[0067] It is understandable that the shutters of the louver-type exhaust port are angle-adjustable, which can adjust the direction and speed of odor flow. When the wind direction is different in different seasons, the angle of the shutters can be adjusted in advance to achieve a better odor suction effect.

[0068] In some embodiments, as Figure 2 As shown, the exhaust port 11 of this embodiment is protruded from the floor of the toilet room 1 and is inclined relative to the floor of the toilet room 1 .

[0069] It can be understood that the exhaust port 11 of this embodiment is arranged on a boss on the ground, so that the height of the exhaust port 11 is slightly higher than the ground. When there is water on the ground, it will not enter the exhaust pipe 41 through the exhaust port 11, thereby avoiding the impact of the running water on the exhaust pipe 41, which is beneficial to improving the service life of the exhaust pipe 41. In addition, the boss where the exhaust port 11 is located is arranged to be inclined with respect to the ground, which is beneficial to guiding the running water on the boss to automatically flow out, and can also be beneficial to the suction of odor.

[0070] In some embodiments, as Figure 1 As shown, the ventilation system 4 of this embodiment further includes a check valve 45 .

[0071] The check valve 45 is disposed at one end of the exhaust pipe 41 close to the exhaust pipe 42 .

[0072] It is understandable that the check valve 45 of this embodiment is arranged on the main pipe connecting the exhaust pipe 41 and the exhaust pipe 42. The check valve 45 can only allow odor to enter the exhaust pipe 42, and does not allow odor to flow back into the exhaust pipe 41, ensuring that odor will not enter the toilet house 1 through the exhaust pipe 41, and the odor in the septic tank 3 will not enter the toilet house 1, thereby ensuring the quality of the air in the toilet house 1.

[0073] In some embodiments, as Figure 1 and Figure 2 As shown, the exhaust pipe 41 of this embodiment includes a main pipe and a plurality of branch pipes.

[0074] One ends of the plurality of branch pipes are respectively communicated with the plurality of exhaust ports 11 , the other ends of the plurality of branch pipes are communicated with the first end of the main pipe, and the second end of the main pipe is communicated with the exhaust pipe 42 .

[0075] It is understandable that when there are multiple exhaust ports 11, the exhaust pipe 41 includes a main pipe and multiple branch pipes. The first ends of the multiple branch pipes are connected to the multiple exhaust ports 11 one by one, and the second ends of the multiple branch pipes are connected to the main pipe, which is then connected to the exhaust pipe 42. The odor enters the main pipe at the same time through the multiple branch pipes, and then enters the exhaust pipe 42 through the main pipe.

[0076] Furthermore, the check valve 45 of this embodiment is provided on the main pipe to ensure that the odor in the exhaust pipe 42 does not flow back into the exhaust pipe 41 .

[0077] In some embodiments, as Figure 1 As shown, the air blower 44 of this embodiment is arranged in the middle and lower part of the toilet room 1.

[0078] It can be understood that the blower 44 is arranged in the lower middle part of the toilet room 1, and the blowing direction of the blower 44 is toward the bottom of the toilet room 1, so that the wind curtain formed by the blower 44 blocks the rising odor, prevents the odor from escaping upward, and reduces the amount of odor entering the human nasal cavity.

[0079] In some embodiments, as Figure 1 As shown, the air blower 44 of this embodiment is a cooling and heating air blower.

[0080] It is understandable that the cooling and heating fans can supply air according to the seasons. In winter, the cooling and heating fans activate the warm fan to supply air. The warm air not only prevents the escape of odor, but also increases the temperature in the toilet room 1, increasing the comfort of going to the toilet; in spring, summer and autumn, the cooling and heating fans activate the normal temperature fan, which not only prevents the escape of odor, but also increases the air circulation in the toilet room 1, increasing the good feeling of going to the toilet.

[0081] In some embodiments, as Figure 1 As shown, the ventilation system 4 of this embodiment further includes: an unpowered fan 46.

[0082] The unpowered fan 46 is disposed at the top end of the exhaust pipe 42 .

[0083] It is understandable that the unpowered fan 46 of this embodiment can be an unpowered wind hood, which is arranged at the top of the exhaust pipe 42. It can rely on natural wind and indoor and outdoor air convection to achieve ventilation. It can achieve continuous operation without relying on electric drive, save energy, and facilitate the discharge of odor from the top of the toilet room 1 through the exhaust pipe 42.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
