Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to an odorless toilet. Background Technology

[0002] As people's living standards improve, their demands for hygiene also increase. Whether at home or in public places, the hygiene of toilets is an important criterion for judging the overall level of environmental hygiene. Among these factors, toilet odor is closely related to the evaluation of toilet hygiene.

[0003] To address toilet odors, besides using fragrances, incorporating deodorizing functions into the toilet bowl is another solution. Existing toilets typically have a suction / exhaust fan assembly with an air outlet facing the side of the bowl. At the air outlet of this assembly is an absorbent layer filled with materials like activated carbon to absorb odors. However, because toilets are relatively humid, toilet odors are often stronger than in other living spaces. Therefore, the absorbent layer's effectiveness is significantly reduced, requiring frequent replacement. Utility Model Content

[0004] The purpose of this invention is to provide an odorless toilet that deodorizes more thoroughly and is more convenient.

[0005] To achieve the above objectives, this utility model proposes an odorless toilet, including a toilet body and a cover. The toilet body includes a sewage discharge chamber and an installation chamber located at the rear end of the sewage discharge chamber. The lower end of the installation chamber is provided with an "S"-shaped sewage pipe, and the upper end of the installation chamber is provided with a suction and exhaust fan assembly. The suction and exhaust fan assembly includes a first extension section communicating with the sewage discharge chamber and a second extension section communicating with the sewage pipe. The end of the first extension section is a suction port, and the end of the first extension section is located on the toilet body and is not higher than the upper surface of the toilet body.

[0006] Preferably, a water outlet is provided on the side wall of the sewage chamber, and the end of the first extension section is installed on the side wall of the sewage chamber of the toilet, so that the air intake is also provided on the side wall of the sewage chamber and is arranged adjacent to the water outlet.

[0007] Preferably, the air intake is located above the water outlet, and the height difference between the air intake and the water outlet satisfies the condition that water will not enter the air intake during the flushing process of the toilet body.

[0008] Preferably, a waterway is provided along the water flow direction of the outlet, and a sewage outlet communicating with the sewage pipe is provided at the bottom of the sewage discharge chamber.

[0009] Preferably, the front end of the drain pipe includes a water seal section for forming a water seal with the drain chamber, and the second extension of the suction and exhaust fan assembly is connected to the rear end of the water seal section.

[0010] Preferably, the toilet body has a receiving groove located between the sewage chamber and the installation chamber, and the end of the first extension is disposed in the receiving groove.

[0011] Preferably, the end of the first extension section is a flat structure, forming a long strip-shaped air intake.

[0012] The beneficial effects of this utility model are as follows:

[0013] The toilet body has an air intake connected to the exhaust fan assembly in the sewage chamber to absorb the exhaust gas in the sewage chamber. The exhaust gas in the sewage chamber is not easily dispersed into the environment, making the toilet smell fresher. Attached Figure Description

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] See Figure 1As shown in the figure, as a preferred embodiment of this utility model, an odorless toilet is proposed, including a toilet body and a cover. Only the toilet body is shown in the figure; the cover is a conventional design, and any cover that can be adapted to the toilet body can be used in this utility model. The toilet body includes a drain chamber 2 and an installation chamber 1 located at the rear end of the drain chamber. The installation chamber 1 is provided with an "S"-shaped drain pipe 13 and a suction and exhaust fan assembly 11. The drain pipe 13 is located at the lower end of the installation chamber 1, and the front end of the drain pipe 13 is connected to the drain chamber 2 through a drain outlet 21 located at the bottom of the drain chamber 2. The rear end of the drain pipe 13 is connected to the sewer. To prevent the odor from the sewer from flowing back into the drain chamber 2, a water seal section is formed between the front end of the drain pipe 13 and the drain chamber 2 to isolate the odor from the sewer. The suction and exhaust fan assembly 11 is located at the upper end of the mounting cavity 1. The suction and exhaust fan assembly 11 includes a first extension section 111 and a second extension section 112. The first extension section 111 is connected to the sewage discharge cavity 2, and the end of the first extension section 111 is the air intake 23. The end of the first extension section 111 is not higher than the upper surface of the toilet body, so that the installation of the toilet seat will not affect the installation of the toilet seat. The second extension section 112 of the suction and exhaust fan assembly 11 is connected to the sewage discharge pipe 13 and is connected to the rear section of the water seal section of the sewage discharge pipe 13.

[0021] The foul odor drawn in by the air intake 23 is discharged into the drain pipe 21 through the second extension 112 of the air intake and exhaust fan assembly 11. A check valve (not shown in the figure) is provided in the first extension 111 to prevent the foul odor from flowing back from the air intake and exhaust fan assembly 11 into the drain chamber 2. A water outlet 22 is also provided on the side wall of the drain chamber 2. A water channel 24 is provided along the water outlet 22 in the direction of water discharge, so that the water can flow along the water channel 24 through the inner peripheral wall of the drain chamber 2, which is conducive to cleaning the filth in the drain chamber.

[0022] In this embodiment, the air intake 23 is also disposed on the side wall of the drain chamber 2, adjacent to and above the water outlet 22. During toilet flushing, water will not splash into the air intake 23 as it flows along the waterway 24. Simultaneously, the upper end of the mounting cavity 1 has a horizontally extending mounting groove 12, the front end of which communicates with the rear end of the drain chamber 2. In other embodiments, see [reference needed]. Figure 4 Alternatively, the air intake 23 can be placed in the mounting groove 12, which can also achieve the effect of absorbing odors. In order to further improve the efficiency of odor extraction, the end of the first extension 111 in this embodiment is a flat structure, which can form a long air intake 23', thereby increasing the air intake area and improving the air intake efficiency.

[0023] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
