Description
Technical Field
[0001] The utility model relates to the technical field of toilet deodorization, in particular to a toilet deodorization and exhaust system. Background Art
[0002] In the prior art, the odorous gas around the toilet is guided into the water curtain assembly through the air inlet assembly for purification. The air filtered by the water curtain assembly then flows to the air outlet assembly area, which is integrated with a sterilization device to ensure that the air is sterilized and deodorized before being released back into the toilet environment, thereby achieving the deodorization effect of the toilet. The prior art has the following problems: (1) There may be a risk of secondary pollution: If the filter device is used for a long time and is not maintained and cleaned in time, bacteria, mold and other microorganisms may breed inside it, causing secondary pollution, or if the sterilization device fails, the polluted air will be discharged back into the room, losing the sterilization effect. (2) Increased parts cost and maintenance cost: If an internal circulation air duct is used, a filter module must be added, and a sterilization module may also be added, which will increase the product cost and lead to an increase in the price at the customer end; at the same time, it may need to be replaced regularly, or if it breaks, it needs to be repaired, which will increase additional maintenance costs. Utility Model Content
[0003] The present invention aims to solve at least one of the above-mentioned technical problems in the related art to a certain extent. To this end, the present invention proposes a toilet deodorizing and exhausting system.
[0004] To achieve the above purpose, the technical solution of the utility model is as follows:
[0005] According to the first embodiment of the present invention, the toilet deodorization and exhaust system includes a toilet, a bathroom heater and a deodorization pipe. The deodorization pipe is arranged outside the toilet, and a deodorization air duct is arranged inside the toilet. One end of the deodorization air duct is connected to the toilet cavity of the toilet, and the other end is connected to the deodorization pipe. The bathroom heater includes a shell, a first exhaust fan and an air inlet pipe. The shell is provided with a first air inlet, a second air inlet and a first air outlet. A first air guide shell is provided in the shell. The first exhaust fan is arranged in the first air guide shell. The first air guide shell is provided with a third air inlet. The wind shell is arranged to form an exhaust duct, the outlet of the exhaust duct is connected with the first air outlet, the first air inlet and the second air inlet are located outside the exhaust duct, the exhaust duct is connected with the internal space of the shell through the third air inlet, the second air inlet is connected with the deodorization duct, the first air inlet is connected with the indoor space through the air inlet pipe, a damper blade is provided in the first air inlet, and the damper blade can be rotated to open or close the first air inlet, and the ratio of the diameter d1 of the deodorization pipe to the diameter d2 of the air inlet pipe is d1 / d2<1 / 2.
[0006] The toilet deodorizing and exhausting system according to the embodiment of the utility model has at least the following beneficial effects:
[0007] 1. The utility model changes the deodorization of the toilet from internal circulation to external circulation by sharing the exhaust duct of the bathroom heater. The air duct is switched by the air valve blade. When the air valve blade rotates to the horizontal position, the first air inlet is fully opened. Since the deodorization duct is long and thin, the diameter of the deodorization duct is smaller than the diameter of the air inlet duct, which makes the pressure loss of the deodorization duct relatively large. The indoor wind will enter the internal space of the shell from the first air inlet, then enter the exhaust duct through the third air inlet, and finally be discharged to the outside from the first air outlet. At this time, it is the same as the ventilation mode of an ordinary bathroom heater and is suitable for bathing and dehumidification scenarios. When the air valve blade rotates to the vertical position, the first air inlet is completely closed. The pressure loss of the first air inlet is infinite. The wind enters from the toilet end, enters the internal space of the shell through the deodorization duct and the second air inlet, then enters the exhaust duct through the third air inlet, and finally is discharged to the outside from the first air outlet, realizing toilet deodorization. It is suitable for toilet scenes with strong odor. In addition, the rotation angle of the air valve blade can be controlled to control the flow area of the first air inlet, so that the pressure loss of the first air inlet and the deodorization pipe is basically the same, allowing air to enter both the first air inlet and the second air inlet, which can achieve ventilation in the bathroom and deodorization of the toilet.
[0008] 2. The utility model guides the odor from the toilet directly and effectively into the external deodorization pipe, which is then discharged to the outside. This process cleverly bypasses the dependence on the filtration module and the sterilization module, fundamentally eliminating the risk of secondary pollution from the source, and ensuring the purity and hygiene of the environment; it can also save the cost of parts for the filtration module and the sterilization module, which benefits the customers; at the same time, it also does not require customers to perform regular maintenance, reducing their maintenance costs.

DETAILED DESCRIPTION
[0025] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.
[0026] Reference Figure 1-4A toilet deodorizing and exhausting system includes a toilet 100, a bathroom heater 200, and a deodorizing pipe 300. The deodorizing pipe 300 is arranged outside the toilet 100, and a deodorizing air duct 110 is arranged inside the toilet 100. One end of the deodorizing air duct 110 is connected to the toilet cavity 120 of the toilet 100, and the other end is connected to the deodorizing pipe 300. The bathroom heater 200 includes a shell 210, a first exhaust fan 220, and an air inlet pipe 230. The shell 210 is provided with a first air inlet 211, a second air inlet 212, and a first air outlet 213. A first air guide shell 240 is provided inside the shell 210. The first exhaust fan 220 is arranged in the first air guide shell 240. The top and bottom of the first air guide shell 240 are opened. The third air inlet 241 is enclosed by the first air guide housing 240 to form an exhaust duct. The outlet of the exhaust duct is connected to the first air outlet 213. The first air inlet 211 and the second air inlet 212 are located outside the exhaust duct. The exhaust duct is connected to the interior of the housing 210 through the third air inlet 241. The second air inlet 212 is connected to the deodorizing duct 110. The first air inlet 211 is connected to the indoor space through the air inlet duct 230. A damper blade 400 is provided in the first air inlet 211, which can rotate to open or close the first air inlet 211. The ratio of the diameter d1 of the deodorizing duct 300 to the diameter d2 of the air inlet duct 230 is d1 / d2<1 / 2. Furthermore, the ratio d1 / d2 of the diameter d1 of the deodorizing duct 300 to the diameter d2 of the air inlet duct 230 is 1 / 2.5-1 / 2. In this embodiment, the deodorizing air duct 110 is arranged inside the movement of the smart toilet 100. The front end of the deodorizing air duct 110 is connected to the toilet cavity 120 of the toilet 100, and the rear end extends out of the toilet 100 and is connected to the deodorizing pipe 300. The deodorizing pipe 300 can be buried in the wall. The diameter of the deodorizing pipe 300 is about 40-50mm, and the diameter of the air inlet pipe 230 is about 100mm. The bathroom heater 200 is installed on the ceiling 500 of the bathroom. The deodorizing pipe 300 extends upward to the ceiling 500 and is connected to the second air inlet 212.
[0027] Working principle: By sharing the exhaust duct of the bathroom heater 200, the internal circulation deodorization of the toilet 100 is changed to external circulation deodorization, and the air duct is switched using the air valve blade 400. When the air valve blade 400 rotates to horizontal, the first air inlet 211 is fully opened. Since the deodorization pipe 300 is long and thin, the diameter of the deodorization pipe 300 is smaller than the diameter of the air inlet pipe 230, so that the pressure loss of the deodorization pipe 300 is relatively large. The indoor wind will enter the internal space of the shell 210 from the first air inlet 211, and then enter the exhaust duct through the third air inlet 241, and finally be discharged to the outside from the first air outlet 213. At this time, it is the same as the ventilation mode of the ordinary bathroom heater 200, and is suitable for bathing and dehumidification scenarios. When the damper blade 400 rotates to a vertical position, the first air inlet 211 is completely closed, and the pressure loss of the first air inlet 211 is infinite. Air enters from the toilet 100 end, passes through the deodorization duct 300 and the second air inlet 212, enters the internal space of the housing 210, then enters the exhaust duct through the third air inlet 241, and finally is discharged to the outside through the first air outlet 213, thereby deodorizing the toilet 100. This is suitable for toilets with strong odors. In addition, the rotation angle of the damper blade 400 can be controlled to control the flow area of the first air inlet 211, so that the pressure loss of the first air inlet 211 and the deodorization duct 300 are basically the same, allowing air to enter both the first air inlet 211 and the second air inlet 212, thereby achieving both ventilation in the bathroom and deodorization of the toilet 100.
[0028] In some embodiments of the present invention, an air inlet end of the first exhaust fan 220 faces the third air inlet 241 .
[0029] In some embodiments of the present invention, the first air inlet 211 and the second air inlet 212 are provided on the side wall of the housing 210. The deodorizing duct 300 and the air inlet duct 230 are connected to the side wall of the housing 210, reducing the occupied space above the ceiling 500.
[0030] In some embodiments of the present invention, the bathroom heater 200 also includes an air inlet panel 250, which is installed on the indoor ceiling 500 and located next to the shell 210.

[0031] In some embodiments of the present invention, a rotating shaft 410 is provided on the damper blade 400, and the damper blade 400 is horizontally arranged in the first air inlet 211 via the rotating shaft 410. The outer profile of the damper blade 400 is adapted to the inner peripheral wall of the first air inlet 211.
[0032] In some embodiments of the present invention, a motor 420 is provided outside the first air inlet 211 and connected to the rotating shaft 410. The motor 420 is used to drive the rotating shaft 410 to rotate.

A fourth air inlet 281 is provided at the top of the second air guide shell 280. An internal circulation duct is formed by the second air guide shell 280. The outlet of the internal circulation duct is connected to the second air outlet 214, which is connected to the indoor space through the internal circulation duct 270. The first air inlet 211 and the second air inlet 212 are located outside the internal circulation duct, which is connected to the interior space of the housing 210 through the fourth air inlet 281. The air inlet end of the second exhaust fan 260 faces the fourth air inlet 281. When internal circulation is required, the second exhaust fan 260 is turned on, and air enters the interior space of the housing 210 through the first air inlet 211, then enters the internal circulation duct through the fourth air inlet 281, and is discharged into the indoor space through the second air outlet 214, thus completing the internal circulation. The internal circulation can be used for both the heating and blowing modes of the bathroom heater 200. The present invention provides a second air inlet 212 on the existing split-type bathroom heater to connect to the deodorization duct 300 without affecting the original functions of the bathroom heater, such as ventilation, heating, and blowing.
[0034] In some embodiments of the present invention, the bathroom heater 200 further includes a heating module installed in the second air outlet 214. When the heating module is turned on in the heating mode, the air in the internal circulation duct is heated by the heating module before being discharged, and the hot air is blown out to increase the indoor temperature.
